Rapunzel, you are correct, I do suffer from anxiety too...it is a struggle with the "fight or flight" response because I tend to choose the latter and then I fell guilty about it.
justfloating, I know exactly what you mean! sometimes I simply don't have to energy to deal with ppl. Relationships are hard work and sometimes it's difficult to find the energy to work on them, especially when you are just starting off with someone (and I mean friendships, romantic relationships are a whole other thing that I am not ready for right now). I also totally get what you mean about bursting into tears and about concentrating.
BeautifullyMistaken, I did such a good job pretending everything was fine with people I interacted with that everyone was shocked when I had to go on medical leave. No one was aware of the pain and the disfunction I was going through because after a long crying session feeling like I had no reason to live, I would suck up the tears and put on a front so I could make it through class with out completely losing it in front of everyone. As you can imagine, this led to a great amount of emotional instability.
