Oh, dear. Well, trade school isn't for "idiots." That's a common line of BS they fed our generation-- I think it was a conspiracy to make money from dragging more people to college. It's for people who don't care for or mesh with the college career world and don't care to spend their working years pushing a broom or shoveling fries.
Wish I'd told all the people who said I was so smart I had to go to college to piss off and gone to trade school instead. I'd be a mechanic or carpenter or something I'm actually interested in instead of having a liberal arts degree that bores the s**t out of me.
Sounds like you'll be well shut of your folks the minute you are of age, OP. Their problems aren't your fault. I have some sympathy for your dad-- being what everyone else wants to see is exhausting and leaves nothing for the ones you really love-- but it was his choice for whatever reason to do that, so my sympathy is also limited.
