@otakujome, I think it would be good for you to be aware that you've probably got three things going on right now.
One, you have unresolved trauma that you haven't been able to get good therapy for - and you are under a lot of stress because your trauma environment - school - is something you go to every day.
Two, you are a 14 year old male - so you are going through a big hormone/growth blast right now. That, all by itself, makes people sometimes want to jump out of their skin.
Three, your communication with your parents isn't very good, and they aren't relating to you in helpful ways right now. So you are lacking in a positive adult authority-figure/go to for help person. You found this forum, and I think we can stand in for some of that need, but not all of it.
You do need to learn better coping skills. I think you should give those a real solid try before you can say that you need daytime medication to make coping possible for you. Meds are always used to
help the ability to cope, they can't be relied on to
replace the ability to cope. Especially, especially the addictive ones. (and I know you've heard this already, but it can't be said enough).
Would you be willing to actually work with a therapy workbook? Maybe a PTSD thing, maybe a CBT or DBT thing? It's not easy to do on your own, but it would give you a structure for learning new ways to understand and cope with your emotional/trauma-based responses to things, and you might start to get some real, sustainable relief.
There is no cure for the hormone thing except getting older; and I don't mean to diminish your trauma responses
at all - you just need to remember that you also have basic hormone turbulence as well.
