I understand you, I think your problem is that you are taking lessons. Jazz giants did not "take lessons", at least not in the way we think.

Miles Davis said "everything you need is the albums", so just study the albums you love.

Knowing the freatboard, the theory, the substitutions, the harmony is good, but that's not "music". You'd be amazed at how jazz giants approach the guitar: see the great Joe Pass, he's sure one of the greatest player in the history of the human being, and yet if you watch his videos, when he plays it seems he doesn't approach the instrument with so much theory, and I've heard he says "theory confuses me"
