I've only been playing Bass again for about 5 months after playing in my teens a bit and I'm loving it, I probably play/practice/learn about 2 or 3 hours a day (sometimes more!), I try to structure my playing session with a certain amount of time on scales arpeggio's, an hour or so learning songs via YouTube and probably an hour just noodling on the bass and writing down on post-it notes ant little bass riffs/runs I make up.
Anyway my advice is stick at it and try not to put pressure on yourself, a short break from playing might help as others have suggested and you might also see if you do miss playing bass or not.
Good luck
John
