I disagree that you don't have a repertoire based on what you wrote. You probably have more than you think.
The word usually means the range of skills you have. If you did TAB before then getting that back will enable you to play a big body of work - but the amount music is not repertoire, it is your ability to play them, so maybe it will include many styles, genres etc. Earlier some folks were on my case because I do not like TABs, but notation is how I learned.
So if you can read TABS on say funk. rock, folk - then you're repertoire stylistically already covers those genres.
Just get back to it.
