Hi, I'm not a lesbian but I remember being bullied by my young girl friends bc I didn't feel attracted to a boy that was very popular at the time, lol, so in a way I understand you being upset for the feeling of not being able to be attracted to something.

I'm sorry you are going through this and I don't have many advices since, as I said, what I went through, though slightly similar, it's far less serious. My advice at the moment is to perhaps find other friends that you can relate to better so you don't hyperfocus on the friend group you feel as though you don't fit in. I have some friends in my college that I feel like I'm a stranger, but that feeling dies down because I know I have another group of friends that actually know me and accept me and I can be myself and still belong, that comforts and makes you feel more in tune with yourself, so perhaps try broadening your friend group so you can also find your peace of mind with people that don't make you feel so astray, allowing you to not think too much how you don't belong to another group, because you know there is another that will always welcome you with open arms.

That would be my advice, I'm sorry it may not be the best, but I do hope it helps somehow
