This is some seriously great advice
Well said!!! Also, TAKE HEART!! This question comes up more often than you might think and your experiences are shared by many if not all here at GMC at some point in their journey towards becoming "Better".
Follow Ben's advice here and you can work through the slumps/plateaus, as they too are a natural part of the process. Not a fun part, but a natural part none the less
I feel your pain on playing in a band your not in love with. Thankfully, there is usually something to like in nearly every band. In this case it's jamming with your mates
I was a bass player in a blues band for a while (The Dillon James Band), then a guitar player in a Girl fronted indie rock band (Skye Clad), etc. and in each one there was something that made it worth doing and something to take away when it was over.
So relish the experiences as they come, be patient with yourself, and try to break things down in to small enough bits that each one is something you can do without stressing. Music is a wonderful thing and sometimes we get so driven to move forward we forget to enjoy it ;0)

I don't know of any books about that, most musical auto biographies usually skip the actual musical stuff !
I usually find that plateaus and slumps occur when we don't have a reason for what we're doing.
Having a band to play in is cool but I bet that being in an indie rock band there is little need for sweeps, picking etc.. so you might possibly have a conflict between what you're playing and what you want to play ?
The best way out of the forest is not to focus on wide, all encompassing goals but very small steps instead. Maybe spend a week on just one technique or lick ?
If you have small, achievable (almost easy) goals then you increase your chances of actually achieving them and then giving yourself motivation. As guitarists, we need to see results don't we or we get discouraged ?
So the best way to give yourself results is set goals that you KNOW you can complete in a few days or a week's worth of practise.
