I once got kicked out of the house in the middle of Feb., in -35degC weather. I deserved it though. They found me curled up in a ball on a bench, out cold, at 3am. If I would have stayed out all night, I probabky would have froze to death.

Anyways though, sounds like your mom is losing her memory a bit and doesn't really realize it. I'm sure she's not doing this on purpose, but maybe she's starting to get Alzheimers. Seems like a sign to me.

Who knows though, but you're 18, and it's time to start your own life. I suggest finding a place to live, getting full time work, and when you get on your feet and get some checks rolling in, maybe consider a student loan for college, or save up enough cash for college, but that can be hard paying rent and living.

Anywho, good luck to you, sorry your mom is going crazy. But it's time to start life now.
