hi im sorry you had to go through that i have no experience in SH but to cover up scars on ur wrists u can wear bracelets , wear long school shirt to cover ur arms wear a school jumper, makeup or u can mabye draw over them ik u could possibly get ink p0i5oning but try use a non toxic pen like a whiteboard pen . i hope ok because no one deserves this. if u are 18 u have the free will to move out legaly. im sorrry if this didnt help but i hope ur doing well :)
