Well.. I have a diagnose for that... so pills...
But, exercise helps! My favourite now is scuba! One hour under water and I am a new man! Depression is gone, anxiety gone and - strange enough - I have noticed I get a boner when under water (true). I might have a fish fetish
The Wife like it.... the boner, I mean!
Drinking and drugs is a BAD idea! The King of Queens also cheers me up
