I suggest you follow your own feelings, that is, stop for the moment and be aware of your reaction. The fact that these seances become disagreeable probably means you're getting an overdose, overloaded with this treatment, cool it for a while, then start again with smaller doses.

I can point you in a direction but you must walk the path, mediation can clear the self of doubt fear and anxiety simply by releasing negative energy with each breath. (It cured me of deep depression and suicide.) Those subliminal messages will only mask the turbulence of your soul, telling you that things will be better is just another lie if you're not realizing what causes these symptoms releasing it, then clearing you psyche/soul with meditation.
My personal remedy takes a walk within nature, somewhere you find particularly beautiful, take out your cell phone, play some meditation music on YouTube, find a place where you can be alone, sit then close your eyes. Put yourself in a state of calm, while breathing in through your nostrils out through your mouth, once you find a state of tranquil,simply release what dose not feel positive within each breath in and out like waves on a beach,let it wash away, do this 3 times a week are more if needed and you will begin to find inner peace, this technique again saved my life so its worth a shot brother are sister...
