Pain can change anyone

It can depend on what type of pain you take. Physical pain, mental pain, imaginary pain, exaggerated, it doesn't matter it can all change you. I have gone through severe mental pain, I am currently going through severe physical pain, and I don't know if it's real. It feels real, but the brain can do funny things.
Somehow I think it's all connected. Physical pain can cause mental anguish, then it can bring paranoia of more pain and the stress from that brings exaggerated pain and eventually, you expect it and it comes, sometimes from stress and it's real, but other times, it's the brain being funny and making imaginary pain.
I have a roommate that has a severe chest problem. It hurts him sometimes but not enough to do anything about it. He stresses about it and cause undo pain. Most of it seems to be imaginary because he wants attention. It flairs up most when I am in pain. It seems like he wants to out do me. I think this is a mental problem brought on by years of chest pains and getting that attention and now that someone else is in pain worse then his, he exaggerates his to get that attention back. I don't think he does it on purpose, but reflexively.
The pain I am going through I am sure is affecting me mentally. I am angry, depressed, lonely, etc, because I can't walk and I can barely hold myself up sometimes. I know I am sad it's happening, I am snappier then normal. But I am also more observant of myself then earlier years. So I can pull myself out of slumps if I have help and I usually do. If you read my other blog you will see literal mad ravings of a lunatic. Now a days am in a better place even with extreme going on. I am older, better able to handle them and see warning signs of falling into something I can't pull out of. I still feel those things I have talked about in my other blog but I can control them. I can hold my tongue when needed most. I can talk out my problems.
But as I said previously, pain can change a person. The last major pain I went through was mental and helped my grow up and see myself as I truly was. This physical pain however, I don't know how it's going to change me, but I'm sure it's already started.
