There is nothing wrong with you. Everyone ad their ups and downs
This is a process that happens in most humans. most often happening to teenagers due to their increased hormones during their puberty. I would recommend getting attached to music as a form of reliance. I too had my days when I would be depressed but I got through it by attaching myself to something rather than someone. people's actions in real life during this time can seem exaggerated to you so it would be best to just ignore people for now if you are sensitive and just listen to music, study, or read a book to take your mind off the stress. However, based on the current trends I would recommend you to get attached to this thing called Kpop. recently I conducted a survey and many people said they were happier watching stuff about pretty people rather than going out and socializing. you could attach yourself to a particular idol and "stan" them as it would keep your mind off people. however, this method although effective can lead you to become a brain dead fan who will waste money and become a loner I suggest that if taking this idol attachment approach that you go out and try to connect with new people or try to reunite with your old people too so that you don't lose touch with reality. And lastly, it could be just that this Current situation stress is weighing too heavily on you and you have mistaken it and you just need a period of rest to get your bearings back. I recommend you try a period of resting and self-indulgence, then if that doesn't work music, and if the music doesn't work then attach yourself to an idol. Don't give up and try something new
