Philippe (? sorry, bad memory
, I agree with a lot of advice given here about:
1. Taking a break to freshen up
2. Finding someone to jam with / find a band etc.
It seems to me that, like me, you are a kinaesthetic learner. If I don't do something directly for myself I don't learn. Exercises don't engage me. Nor lessons or books. The only time theory has engaged me was to solve a particular musical problem that bugged me.
If you don't aim to be a pro the focus has to be on enjoyment or it's just silly. That means finding the joy of playing even if you commit the seemingly "cardinal sin" of sloppiness.
There has long been a trend towards greater perfection with the evolution of technique and the standards set by machines. Yet perfection - in music and every other area of life - brings no happiness. More usually, perfectionism is a destructive force that sucks the joy out of everything it touches. Sound familiar?
Think of it this way. A lot of the "perfect" music I have heard lacks sincere expression - akin to a politician flawlessly reciting meaningless platitudes. Most of us would much rather hear a sincere layperson give real insights punctuated with stumbles, stutters, ums, ers and "unprofessional" pauses.
I have much more fun with old music (or retro new music) - music that says it's okay for tempos to shift around, that it's okay to focus on expression, feel, sound and imagination at the expense of accuracy - though I say this with a big proviso ...
as long as everyone in the band does it together as a team to help the song tell its story.
Moonie. Mitch. John Densmore. All have been lambasted by some people for "sloppiness" - even Bonzo - but their performances are loved my many for their passion and integration with the band and the music.
So, from a non pro standpoint, just get with a bunch of people you like as human beings and try your best to make them sound good. If you do that you will most likely rediscover your joy of drumming.
That's my cent.
