There is something called Airborn that helps your immune system. This works for alergies and colds.

Also echinacea is good if you already have a cold. Keep garlic and orange juice up.

I know pollen is bad, maybe stay out of outside, keep indoors. Use air conditioning and air filters instead of window fans.

I know the environment can get to me too! I felt like I had a head cold every time I went out or had a window open!

Dragonflybreeze ... your story is absolutely screaming at me.

"at five years old i had an experience that Never should have transpired. The guy was a rotten predator, there was no law of attraction ... simply a messed up man taking advantage of a little girl. This is a crime"... this links together with "an overwhelming uncomfortable feeling of being so close to neighbors.... It is like Claustrophobia, but on a larger scale", and you speak of a "penetrable" shield, and "Like having a glass of purified, sweet water and someone putting dirt into it". Even the name you chose "Dragonflybreeze" fits into the picture of your question ... do i need to continue or do you see the obvious link to all this?

*DragonflyBreeze In this life all we can learn i s Acceptance. That the world does not revolve around us. It revolves around the sun. So to distract ourselves from things that bother us. We must keep our hands and bodies busy. Which in turn will keep the mind to busy to worry. My neighbors are way to close to our home also. So i just pray for them. Then i go on with my work of the day. People who are wealthy can afford to live in expanded spaces. We who are not so wealthy learn survival. Through hard work and Acceptance. Peace Dragon Fly. Stay Strong cause that's all we can do.. "Tere"
