Agreeing whole-heartedly with Tetsujin's answer - it's what I've done dozens of times - but it's not easy to make that first move, and find a band that accepts you. After all, most bands which search for a replacement member will be looking for someone of decent quality. It's rather a Catch 22 situation.
In the meantime, keep learning scales, arpeggios, chords, learn to read at least a chord chart, in time, and listen to as much guitar music as you can. Learn to listen and play back quickly, so in a band situation, you're not the slow one everyone else is waiting for. That's a sure way to have a short stay in any band.
A looper will be a great tool for you to 'make your own' band, sort out your timing, and listen to your efforts in your own time. There are also many, many backing tracks available these days on the 'net, for you to play along to. Learn to discern whether a track deserves maj. pent., min. pent., blues, or whatever set of notes as appropriate.
Go to open mics, probably with a backing track initially, to play a couple of well rehearsed numbers (and that's the place to find other musos!); get used to playing, say, 12 bars in any key/genre thrown at you. All the time listening to what you can bring to the party rather than being the guy who widdles all through each number.
Form even a duo, which can play a full set, and offer it to friends and family, getting a feel for playing in front of a (hopefully) friendly audience.
Another thought occurred: look at some of the electric guitar exams that are available. Rockschool and LCM (formerly RGT) have totally graded systems, which you can pick up at your level. They guide through and offer systematic ladders to climb, whether you take the exams or not. Obviously taking the exams is a better option - yes, they'll cost, but that will concentrate your practice and playing all the better! Even an occasional lesson would then be better than nothing, keeping you on the right track. I've had 'occasional' students do just that, with good results.
