How to go back to school?

So I’m 23 this year and have been graduated since 2015. The only reason I didn’t go to college when I graduated is because I have bad social anxiety and I absolutely loathed school. But I’m realizing it’s impossible to make a living off of only a high school diploma. My GPA was only a 2.7, because I didn’t care about school until my senior year, but when I tried that year I got straight A’s. (I also never took my ACT.) However, in Tennessee there’s a “TN Promise” scholarship, where I can get 2 years for free at a community college. Buuuttt I don’t know if I still qualify for that because I’ve been graduated for a few years.

But I don’t know where to start. I can barely pay my bills working full time right now. My credit cards are maxed out from getting behind on bills. I don’t know what to do. I do NOT want to go to school in person but I want to try online schooling. I have no idea what career field to start but I don’t want anything to do with talking to people.. and it doesn’t help that I have no support system, so it’s only me pushing myself and that’s not going anywhere. Where should I start?
