I feel so fucking depressed

School stresses me out so much, I have absolutey no motivation to do any of the school work, I have all A's and B's, but I'm always missing some assignments. I hate how I have to act normal and be social at school, I hate trying to be someone I'm not. And I feel horrible just trying to interact with people. It's not social anxiety because it's not really feeling anxious, but it's a hard thing to describe. I have hardly any friends because i started pushing them out of my life and I stopped showing any emotion around them or interacting with them. I'm not getting bullied or anything like that, in fact, hardly any people outside of the ones I choose to interact with even know me. I just wanna skip school tomorrow, I feel so fucking bad all the time and my head always hurts, I know this is probably the wrong place to post, but I'm really just trying to vent about school struggles specifically
