Frank,

Anxiety and Depression are the two classic reactions to martial sucker-punches and bombs.

You might want to speak to your counselor about being treated for depression, it's harder to lick than anxiety.

Usually good Cognitive-Behavioral Therapy combined with meds has the best results.

There's a great book called Authentic Happiness by a Cognitive Behavioral researcher that has a lot of good stuff in it about disputing negative thoughts/beliefs.

You'll get there friend. You will.
