18F tired and in pain all the time, can't do anything.

I literally just wake up, then immediately I'm tired and wanna go back to sleep. I sleep for at least 8 hours daily, or even 12+ sometimes. Never enough... I recently graduated from high school, and throughout the entirety of my school years, I just slept. A school day is 8 hours here and I woke up to piss and eat my fucking lunch and maybe even skip that and just sleep. My friends would wake me up for a chat, I'd draw for a quick minute, sleep again. Till 4pm everyday for 4 years. Maybe that messed me up a bit...? I mean imagine sleeping 8-10 hours at night, waking up going to school and napping for another minimum of 6 hours. That's a lot of sleep ig. Anyway, I've been like this since idk honestly I'm just tired. My body aches when I pick up a water bottle that's too heavy, or when I'm sitting and get up. It isn't an excruciating unbearable pain, but I do like to use objects around me as support, otherwise it's a bit uncomfortable. I sometimes go up the stairs like a dog cus I'm too tired to use just my leg strength 😓 it's pretty funny tbh, anyway, I'm so tired mentally and psychically I can't do anything or have the energy to spend time with friends. When I do spend time with them, all I can tell them is "I'm bored, I'm tired, I couldn't do anything yesterday blah blah" I've become so boring. The worst thing is when I have to do house chores. I'll be honest I just avoid them, ik it's irresponsible and I'm an adult now but I'm just too tired, my mom says I'm lazy and good for nothing but I just need some rest ffs. On top of all this shit, i have to deal with proving myself. Proving that im not useless or whatever. Chores are too tiring. Life is too tiring, I don't wanna live if this is what life is. I wish i could break a leg or two so i could actually just sleep and rest for a few months with no one nagging me. Everyone else is living life, talking, going out, being silly teenagers. And I'm here trying to avoid drinking too much so I won't have to get up and pee again. Then I get a headache from dehydration. And it's so hot here too, but my mom only lets me use the ac when it's over 35 degrees. I hate this sm.
