I've been where the OP is and it's not nice. I ended up taking a long break. Didn't pick up the bass for a couple of years. Since I've come back I've experienced such a change in my feelings towards what I play that I don't care where or what it is.
Making music is such a wonderful thing to do. In a rehearsal room, at home, a wedding, a pub, jams, open mic nights l just feel glad to be creating music.
So for me it was a psychological change rather than a musical change. But it only came about in conjunction with major changes in my life. Our experience will be similar but our individual stories different.
I hope @spongebob you rediscover the love of music in a way that suits you. Chemistry between players is so vital, maybe rock up at some informal jam nights and see if you click with someone. Could be a start.
