I don’t think you’re “crazy.” Nor do I think you have a “mental condition.” I think you have a maladaptive way of interacting with people. You want friends and you want to be around people but the way in which you go about it leads you to sabotage the relationship. I attribute this to the possibility that you were never taught boundaries or limitations or you lack appropriate social skills.
If you were my client I would want to know more about how you were raised. Also, what are your parents like? Are they loving and caring toward you or are they indifferent or emotionally neglectful? You mentioned that your father has “temper issues” and has beaten you on several occasions. It would be important to know more about your relationship with your father and what you mean by “temper issues.” This information would allow me to understand the nature of your relationship with your parents. It might also explain how or why you interact with peers in the problematic manner that you do.
You also said that you spend a lot of time isolated in your bedroom. I wonder if this has always been the case or if it is a recent change in behavior. I also would want to know if you have any siblings and if so, what are those relationships like. Again, this would be helpful information to know because it could shed light on how or why this problem developed.
Even if we knew why this problem developed it that would be insufficient to solve your problem. What you primarily need is someone to help you learn a more appropriate way to interact with your peers.
It’s not a matter of there being something seriously wrong with you; it’s a matter of you not knowing an alternative way to behave. Please do not blame yourself for this. It is not your fault. It’s almost as though no one ever taught you the rules of social interaction.
You need someone to coach you on what is appropriate behavior and what isn’t and to guide you accordingly. For instance, it’s not appropriate to steal from people or break their things so that you could fix the problem and be the “hero” in their lives. It’s also not appropriate to expect that your friends will interact only with you and never with others. That is unrealistic.
The good news about this problem is that it is correctable. With the right help and guidance you can alter your behavior in a way that’s more socially acceptable to both you and your peers. I’d suggest you ask your parents to connect you to a counselor. You may not need to be in counseling long and medication would likely be unnecessary. I wish you luck.
