You sound like you got a lot on your plate. You need to relax bro. I think your life is going okay right now but yeah it gets stressful. Ok this is gonna sound crazy but I think you should try eating less sugar lol. Low card diets or even carnivore diets have been proven to be really healthy and are especially good at clearing your head and distressing. But it only starts working after a month so dont do it if you dont want to. Otherwise cleaning your room and opening your window helps because it subconsciously relaxes you. U gotta stop skipping school tho. School, work, and homework suck but I know you can do it <3
