If you're depressed, smoke meth. It will force to release 'feel good' hormone- dopamine into your brain. It can be naturally triggered by eating healthy foods or having a sex. Or better, go see a doctor and say you've ADHD and ask for Adderall or Desoxyn. (Just don't watch porn while being high on amphetamines)

Looks like you jerk off too much so the 'feel good' dopamine have been depleted. Now time to replenish it buddy.

Good Luck.
