It's hard to get interested in things when we feel depressed. I'm really sorry you are feeling so badly. Even if things are pointless it doesn't necessarily mean we shouldn't do them. Not everything will have a point.
I looked at some of your other posts and see that you are trying to get help. I hope that you are getting what you need. You've had it pretty rough.
I saw also that you are looking for some kind of career. Depending on how well you can cope with pressure, these are some jobs that don't need a college education to get started. There is nursing. There are one year, two year and BSN. Nursing is a demanding profession but is full of variety and lots of room for advancement. I was informed by a beautician that her profession is recession proof. It is a masculine as well as feminine line of work. It doesn't take a long time to get trained and I believe it also has room for advancement. Another idea is teaching English as a second language. The initial training last 4-5 weeks and is described as strenuous. It has lots of possibilities for travel. These all would give you a decent living. You won't use up all your education credit but would give you time to figure out what you really want to study.
Until you are a bit stronger you may just want to do some research into these careers. Each one is demanding in one way or another.
I hope you get the help you need soon
