Therapy is utterly useless, boyo. Most people here are just ugly and lack sexual and romantic intimacy. It's normal to feel "depressed" under these conditions, the best you can get is a psychiatrist to prescribe you feel good drugs and that's it. Therapy won't change your looks or solve the ugliness and lack of intimacy problem, which is the root of most people's "depression" here. I think you're projecting because you're a mentalcel, but I'm very skeptic of therapy being able to help even mentalcels.
I will help you: you're extremely young and not ugly. Start approaching like there's no tomorrow, approach hundreds, thousands of foids before giving up. Cold approach, warm approach, internet approach, etc. You'll regret it bitterly if you don't do it when you're older, trust me. Also, you're a fellow Brazilian, enjoy that our country isn't a gigacucked place like Canada or Sweden, you won't get in trouble doing it, you're also underage, so you really, really won't get in trouble.
Unfortunately, there's no way to help an old and ugly guy like me. The only people in a position to do it are women, particularly my type of women, and they won't ever do it.
