I've suffered with anxiety for a few years. Recently a lot of things in my life have changed, including moving soon, a break up, university, etc. It has recently got worse. To the point where I'm constantly on edge, and the slightest thing tips me over. I've also noticed they've progressed and at the drop of a hat, I will have a dry mouth, very tense throat and trembling all over - I never used to have these very much.
Earlier for example my friend got sick from some off food(I have emetophobia), and I completely freaked, I couldn't help it - throat, trembling, dry, breathing, the whole shebang. Even though I knew I couldn't get ill from that... it's like I can't think logically anymore.
