Stress.

I'm starting to feel like I don't do anything right anymore..everything I do I seem to get it in the neck. I currently broke up with my ex David.. and I'm trying to live life and not think about it.. but its because I'm enjoying myself that I seem to be getting shouted at.. but I know its none of his business anymore but I feel like I have to explain myself to him.. I can't handle this anymore! It's starting to drive me to insanity... Cause my brain is in constant overdrive. :'(
