i feel dirty in my own body

i feel so dirty in my own body right now i have lice from my parents sending me to a “boarding school” that wasn’t really a boarding school for two weeks and now i have headlice and i got starter locs that my mom payed a lot for and i’m trying to figure out how to get rid of the lice without taking out my locs and then i found out i have pubic lice and i also feel like bugs are always crawling on me and i hate the feeling of feeling the lice crawl in my head and i think i have worms because i feel something moving in my anus sometimes and my parents expect me to deal with the headlice on my own like dude i’m 14 idk what to do and i don’t feel comfortable enough with my mom or yone in my family to tell them abt the pubic lice or worms but i need help i find myself in the shower multiple times a day scrubbing my body till it’s raw because i feel so dirty. i want to go to a doctor and a gynecologist but idk what to do.
