I don't know about "addiction" of emotions, but for sure they can become a habit.

Have you ever had a comfortable pair of jeans or perhaps a really soft, favorite blanket that you liked and used, or wore, all of the time? Eventually they aren't serving you anymore, because they wear out....get holes, fray and so forth. You know they aren't what they used to be and don't look so good, but you hang onto them anyhow because they are familiar and comfortable.

It's the same with feelings. Sometimes they get familiar and comfortable and old. And even when they aren't serving us well, we hang onto them. They take so little effort to maintain because we are used to them.

But just like the old clothing or bedding, eventually if you want something better, you have to throw away the old stuff.

In my personal experience, this is true. I actually loathe in depression. It is a paradox, but I feel comfortbale and 'happy' being there. Therefore, it's no wonder I can't get a girlfriend. Why? My brain is addicted to that feeling of loneliness and rejection/depression, so it'll automatically set itself up for more.

This is where your biggest problem lies Nikulas. Even though you are trying to justify the situation with "being addicted" it is the wrong way to go about the situation regarding your emotions. Negative self talk will only produce more and more negative feelings and outcomes. I've been down that deep dark depression road myself, and it was for a long time so I understand your situation.

The only reason your brain would "enjoy feeling depressed" is because of where your dominant vibration lies. That sounds so cliche from all the similar answers here at IQ but that is pretty much the simple fact of the matter. You really have to work day in and day out at changing your chronic habitual feelings and negative self talk.

I used to go around like a robot stating how much I hated myself, how much of a waste or loser I was and at certain points much worse. It really takes some consistent repetition of positive and uplifting words, feelings and emotion to flip you on the side of the tracks that you desire to be on. I understand how you can feel "addicted" but having that be your justification will only produce more and more of the same. Sometimes we just have to put our foot down and decide to make a change RIGHT NOW.

what method(s) are designed to re-hard wire you emotional circuitry? Meaning, how can I become 'comfortable' being happy so my brain automatically does it's best that I experience happiness?

Change your everyday routine. Once you know you have a habit it becomes a choice. I find myself struggling with this sometimes as well trying to justify the habit or choice but I'm getting better with using it as a forking technique. Let those negative thoughts, feeling, and emotions remind you to turn in the opposite direction. Let them be indicator lights to stop, think, and decide which direction you really want to go in.

Start changing you negative self talk whenever you notice it no matter how hard or stupid it may seem in the beginning stages. Eventually, what felt "out of your comfort zone" will become your new comfort zone. Turn this process into a fun game and see how much you can notice where your emotion is throughout the day and keep track of how many times you flipped it around to a better feeling thought.

Consistency and more consistency is the key here. Your emotions and feelings are the most important things in your life. Focus on how you feel as much as you possibly can and I promise you will start making more and more progress where you want to be.

Think about this for a moment.... consistency and repetition put you into a "addicted" depressed state. Why can't some consistency and repetition in the other direction put you into a "addicted" * good feeling place?

if you let it happen, it will,
some have found a way to call off emotions

get rid of those veils i have talk about this all ready though link to emotion find out the meaning and put them to rest when meditating. reach dhyana.

In the early texts, it is taught as a state of collected, full-body awareness in which mind becomes very powerful and still but not frozen, and is thus able to observe and gain insight into the changing flow of experience.[1][2] Later Theravada literature, in particular the Visuddhimagga, describes it as an abiding in which the mind becomes fully immersed and absorbed in the chosen object of attention,[3] characterized by non-dual consciousness.[4]

The Buddha himself entered jhāna, as described in the early texts, during his own quest for enlightenment, and is constantly seen in the suttas encouraging his disciples to develop jhāna as a way of achieving awakening and liberation.[5][6][7]

One key innovative teaching of the Buddha was that meditative absorption (jhāna) must be combined with liberating cognition.[8]

Just before his passing away, The Buddha entered the jhānas in direct and reverse order, and the passing away itself took place after rising from the fourth jhāna.[9]

In the Pāli canon the Buddha describes eight progressive states of absorption meditation or jhāna. Four are considered to be meditations of form (rūpa jhāna) and four are formless meditations (arūpa jhāna). The first four jhānas are said by the Buddha to be conducive to a pleasant abiding and freedom from suffering.[10] The jhānas are states of meditation where the mind is free from the five hindrances — craving, aversion, sloth, agitation and doubt — and (from the second jhāna onwards) incapable of discursive thinking. The deeper jhānas can last for many hours. Jhāna empowers a meditator's mind, making it able to penetrate into the deepest truths of existence.

Cessation of feelings and perceptionsThe Buddha also rediscovered an attainment beyond the dimension of neither perception nor non-perception, the "cessation of feelings and perceptions." This is sometimes called the "ninth jhāna" in commentarial and scholarly literature.[13][17]

About this, it is said: "Seeing with discernment, his fermentations were totally ended. He emerged mindfully from that attainment. On emerging mindfully from that attainment, he regarded the past qualities that had ceased & changed: 'So this is how these qualities, not having been, come into play. Having been, they vanish.' He remained unattracted & unrepelled with regard to those qualities, independent, detached, released, dissociated, with an awareness rid of barriers. He discerned that 'There is no further escape,' and pursuing it there really wasn't for him."[11]

Someone attaining this state is an anagami or an arahant.[18] In the above extract, the Buddha narrates that Sariputta became an arahant upon reaching it.[19
