I think there are some good points above. Go to sessions, different ones, if they are available. You'll meet new folks, gain 'exposure' among the musician community, hone your skills, and be in the right place at the righttime when things open up and a band member is needed.

Also; don't give up on improving your guitar playing skills - everyone can improve with time and effort. Find a teacher, or use the sessions to watch, listen and learn - then the time between sessions to practice. Good things'll happen!
