nervous breakdown or something like it

What I find most interesting is I know what I've been feeling and most of what I've been feeling I realize that most of it is based on that which is I have not been expressing what I feel and perhaps if I just did a little bit more of that I would have one less head ache a week, one less of everything that is harming to me. I do know I have never pretended to be 'happy' all the time and I ask myself why do I find some things so easy to express to be so raw and honest with and others well the opposite, how does one differentiate.

I seem to be able to tick many of the following symptoms... But then is this not just human? Or maybe my anxiety is just making me paranoid?
