First thing you could do: even if you don't want to restore your relationship, let him know that you're having a very hard time and that you need a chat. Very often, talking about what happened can put you a but at ease.
If you're so angry that you don't want to see him again, go find your friends and cry out. Don't let yourself be eaten up by emotion!
The signs you descrive are the first signs of depression.
Come on, try to find yourself back! Everyone is having a hard time at the end of a relationship. Wish you courage :-)1
