How do I stop masturbating?

There is nothing wrong with masturbating. There's no need to 'regret' your deeds. It's a natural process just like sex, in a way it's simulated sex. However, you seem to be doing it too often. What you need to do is exert control over yourself. You didn't mention your age; I am assuming you’re either in college or school. You need a hobby, something to distract yourself. Go out and have fun. Stop thinking about sex so much. Masturbating can't make you weak, that's a common misconception. You should ideally get a total health check-up, you might be suffering from some nutritional deficiencies for which you should see a nutritionist. There is no reason to feel suicidal about it; it’s not a BAD thing. As a neutral health site we’re not at a liberty to recommend doctors.
