Advice? Don’t do it!! Nah kidding…
Depends where your interests lie. If you fancy becoming a programmer, then take some courses, do some coding in your own time, learn about latest trends. You’d be going up in interviews against people with degrees, doesn’t mean they are better, you may be a better fit to the team/company so don’t let that dissuade you.
If you want to go into the ‘business’ side then look at other roles that support the building of software. In a previous place a tester we hired had no experience whatsoever but was smart, had read up on what the role required and admitted he was taking a punt as a career change. Turned out to be one of the best testers we had after he was mentored through his first few months. Many of the supporting roles can be technical, support engineers who like problem solving spring to mind.
Some places will care about qualifications, and some will be more interested in you and what you are driven by. Worst case is you apply somewhere, get an interview and they say no. You’ve still then had job interview experience (and they all differ).
And as has been said, network! Get on LinkedIn. Read articles, attend free events if you can. Most of IT is knowledge based to get in the door, after that it’s about how quick you learn how ‘things are done’ which is always different place to place.
Good luck! It can be a wonderfully fun and challenging place to work.
