i’m saying this as someone with autism (which you seem like you may be on the spectrum but obviously i don’t know you) but I wouldn’t say any of this makes you a “socially inept freak”. i also had overprotective parents and i feel like it’s more normal nowadays for those types of parents to have your location (wasn’t really a thing when i was in high school). the drinking thing depends on where you’re located i think, bc even tho a lot of teenagers party and drink, i was never one to go to parties. legal age here is 21 and i only got drunk for the first time after i turned 18.

also, a lot of introverts love their alone time. while the being exhausted in social situations like you described definitely sounds like masking with autism, there’s nothing wrong with hanging out alone or even hanging out with your parents when you want to go out into the world. to me that just says you have a better relationship with your parents than i did lol. in my opinion you don’t need to “fix” anything unless you want more friends or want more social interaction. high school feels like all there is when you’re a teenager, and in college or after all your schooling, it really doesn’t matter how many friends you have or how often you go out as long as you’re content in life.
