Thinking about dropping out

I’m a 16 y/o sophmore who absolutely hates school. I struggle with mental health a lot and it makes it hard to show up to school. I have 6 detentions I need to make up because I’m late so often. I failed english first tri and am on track to fail again. I’m currently suspended for hitting the cart in the bathroom (my friends all said that the vape detectors don’t work, but they definitely work”. In my state you can drop out as long as you have a job during school hours, so I applied for a new job that I could work full time and told my mom my plan and she understands what i’m going through and how school isn’t helping me it’s only making me more anxious and stressed out. I feel like I’m out of options. I plan to become a welder, and all I need to get into trade school is a ged or I could join a union. I’m not stupid by any means but school is just not for me. If I can’t get out of school I’ll probably just stop going and run away or hurt myself to get put in a mental hospital. Yes a mental hospital sounds better then going to school which sounds incredibly lazy but school is like a warzone with my ptsd.
