Maybe its time for you to stop thinking too much. Maybe you should just play for fun for awhile. Get with some buds and jam. I always told my students to go home and play with the instrument like it was a toy. Find stuff you like the sound of, no matter what it is. Find a simple groove and jam on for a long time, like a loop. Listen for ways to say it differently, not because you're trying to "conquer" it, but because it feels good, and because you're having a good time. If it helps you to develop a hunger for playing, then you're on your way!
To be honest, I never really practice anymore, not in the traditional sense. I learn things I need to learn, and correct some things, but the rest is playing along by myself (when I'm not gigging or rehearsing with folks) because I want to get into the groove and relish the way I articulate everything. I don't worry about scales anymore, although all my theory knowledge is there in my head. But, for me, it's all about enjoying the feel of playing. I've even been writing songs beginning with the bass part. It makes for music that has a groove from the get-go. Then, I rely on my theory training to create some interesting chord changes, and what not.
Have fun, pal. Stop analyzing how good or bad you are. If you're playing, it's all good. If you mess up, it's alright, too.
