This is really strange but it feels pretty real to me though. I'm 15 and I feel like sometimes I have multiple personalities and I think certain things have to do with them, especially music. If i listen to a specific type, I feel a little more immature and witty and care-free and happy. If i listen to another I feel different, think a little differently I talk different, and act different it seems to me. It's extremely hard for me to put exactly into words what it is but I think it's serious and I think it makes me a little socially awkward. I also pay attention to people around me and feel sometimes influenced by their appearance or attitude. I always think about this and wonder if this is something to sweat about or if its me being weird and hormonal. I just wanted a professionals' opinion. Thank you
