I know this is commonly said but in my case it's genuinely true. People have even told me and worried about me because I lack common sense. I'm 16 but I honestly think I won't be able to make it in the adult world, with no street smarts or really any book smarts. Anything I'm knowledgeable about isn't actually useful. I enjoy writing and music, but I don't feel all that good or competent at either. I'm just really stupid and it shows in very painful ways. I don't help people because honestly I assume I won't do it right, but then they get mad at me for not helping which upsets me more. I don't have any strength and I'm teased about it. I'm terrible at math and get Cs or worse on all of my tests, even when I study ahead of time. I do okay in school but I feel incompetent because my work in my favorite subject, English, is much more average now whereas it used to be praised. I don't know what's happening to me. I can't talk to anyone, I have horrible social anxiety, body dysmorphia and depression and I sit on my phone all day. I only have one friend and rarely go out. I'm vain and care about my apperance way too much. I procrastinate so much even on things I'm passionate about. I can't even drive a car right. I was starting to get better and then suddenly I crashed it so clearly I wasn't as good as I thought. My life feels like a mess. I just feel so stupid and want to cry all the time. My family is mean to me, but I don't even blame them with the way that I act. I'm just such an idiot sometimes it's actually amazing.
