Is it weird that I think that my GA is totally tied to my own feelings of not feeling adequate or worth it?

I just always feel like I am the problem, that no one really likes me they just put up with me, that I am not smart enough or generally not good enough. This makes me panicky. In a sense that I get the shakes, hard to breathe, hard to move, just everything starts to feel intense and like I just want to throw up.

Its been building for awhile now. My stress has gotten so bad that I actually had fits of vomitting. They tested everything health-wise and now I think it is linked to my panic and worry.

Is it just me?
