I wish I had an easy answer for you. I don’t. I do know that what you are describing isn’t that unusual for teens. Learning how to understand and navigate relationships is the most difficult task of adolescence. Feeling alienated and “different” is also pretty common. A lot of your peers are also questioning whether they are “normal”. Many are confused and upset about love relationships. So, please, first of all, give yourself a break.
The best indication that you are healthy is that you want to figure this out. Sadly, the only way you’ve found so far to feel connected is to provoke a negative reaction from others. Yes, it is a kind of connection, but I know that you already know how unsatisfying that is.
I wish you felt safe enough with some other teens to talk about this. I think you’d find that you are more normal than you think. Sometimes youth groups provide that kind of safety. If that’s not an option, then a few sessions with a mental health counselor might be helpful. I suggest this, not because I think you have a mental disorder but because therapy can often provide a safe place for people to work through confusions and to get some support. Please consider it.
I wish you well.
