how do i go back to college?

pick up the phone and make a call

look at college's website and look under the catalog for classes that you want, need. Sometimes a class sometimes a degree can be done online. A lot of four year colleges have distant learning classes and so do community two year college. Just google and search colleges websites.

Find a school you want to apply to, then look up the application process, apply either online or with paper app. Afterwards you will need to contact the other college(s) you have attended to forward transcripts to the school you are applying to. I'd do it on the same day. Most times you will have to pay for that, as well as the application fee. The instructions of requesting transcripts should be on the website(s) of any previous college(s) you have attended. Then its a waiting game to see if you are accepted. Afterwards, the school you have been accepted to will have you come in, or call, to meet with an admissions counselor to get you fully enrolled and classes picked out.

Contact local universities and community colleges.

fill out the fafsa and you might get even more money and then look up the university or college you would like to go to, get things set up to register for classes.
