So done for

So I have my first band concert soon and apparently my dad decides to be present-ish and wants to come and watch it. He only wants to go because he wants to make sure I’m not a failure and not in a supportive way. He said “you better not mess up in any way of sort or else what’s the point of even playing in band?” He criticizes everything. Sports, band, classes, art, skills, you name it. I can’t be good enough in his eyes. I never will be. He calls me useless and stupid all the time. And my family on both sides makes everything my fault. He calls me horrible names and mocks me and yells at me for not being enough. How can I battle grades, band, mental health, and his bs simultaneously? I can’t! I can’t do it anymore! I hate this crap!
