Dude think about it, when normal people get drunk they don't jack off in front of internet friends and cut themselves. You can't blame that on beer (especially under 24 beers). That is not right no matter how drunk you are bud. Alcohol is no escape from the fact that you need to get your ass to a therapist.

nty brah

ill be fine.

didnt even feel the blade

The act is more important than the pain. Cutting yourself rarely hurts. The fact that you're doing it at all makes you need help. The fact that you did it while jacking off in front of a group of people you met over a video game means you REALLY need help. I'm not saying it to make fun of you or anything man but it's just obvious. That's not even a joke it's just a cry for help. Behave this way in front of people you know in real life and see how fast you're at a therapists office.
Without trying to make fun of you, my genuine guess at your root problem is homosexual in denial and ashamed of it

i am bisexual thanks for caring though

a hole is a hole.

Seeing as Alcohol can have strongly varying effects I wouldn't just exclude Alcohol as the main factor that easily, though my post may sounded worse than it was actually meant I just wanted to say there may be a minor problem with his self-esteem. It is also known that Alcohol increases the sexual openness. Whether a 15-year-old drinking Alcohohl is right or wrong is a whole other issue though.
Visiting a psychologist may be worth it anyway though, as he'll probably the only person that will even be able to tell whether a serious issue is at hand.

no problem man, just chill.

ich werde dich erst deep-chillen und dann fressen, huso

You arent a normal 15yr old thats for sure.

not at the moment. not ever really actually.

Even many of the people that have extremely serious mental diseases will say or even think that they are completely normal -- though I am not saying that you have mental problems I just wanted to point out that it doesn't mean much if the person in question says they are fine.
