massive anxiety around money and not sure exactly what it is connected to but I really need help

To start, I am f19 and I am much better off than any 19 year old I know financially. My job is a work from home Supervisor and (because I have spent 0 money since the age of like 6) all my income, as well as birthday and christmas money for the last 10+ years I've saved aside from the car I bought off my parents. I have just over 100K saved up.

The problem is I don't want to spend it, I'm not sure if it is OCD or what but the thought of spending it sounds worse than dying. My parents have drilled into my head that renting is bad because I'm just throwing away money so now I've convinced myself I have to buy a house. In the meantime though I cannot live at home anymore my mental health is in the dumps. I won't give any backstory you can read my million other posts but I can never leave or do anything without some sort of criticism or something else. I have no friends except for one online friend who I can't meet because he is a guy so automatically my parents think I am going to bang him. Insane. Only thing is though I live here rent free and I make $3,749.04 which goes directly into savings.

I don't know what to do, rent is SO expensive and while I have a lot saved I just want to save it and I also don't want to be spending money on something that isn't mine. But I also don't have enough to buy a house just yet and my parents are saying I should wait 1-2 more years until the prices "come down" as if that's a guarantee. I cannot be here for 1-2 more years. I literally don't even feel human anymore with everything I can't do lmao. So im weighing staying in this house that's killing me or losing my money, and I know that once I start spending it I am going to regret it and want to move back in order to save it.

TW sexual abuse:
Does anyone else have this problem with money?

My mom thinks my obsession with money is caused by sexual abuse? for awhile I was basically my pedo grandfather's prostitute without anyone knowing, and he was paying me at like 4 to abuse me. My mom was finding 20 dollar bills in trashcans and she thinks that, because at 4 I associated money with abuse and was throwing it away, once my brain realized that money is valuable my brain is trying to "take control" and not spend a dime in order to make up for the lack of control I had? I have no idea if that's true but I would like to get around this LMAO.
