How do I leave a band

I’ll try and keep it vague to be anonymous.

I’ve been with these guys for about 4 years and one of them I’ve known since elementary school. I live with them all currently and the lease will end soon, I personally like all of them but I’ve always felt like the least musically talented and theory versed. And the drummer and the singer click more together than I do with either of them and it’s always made feel inferior and alienated. I’m not really sold on the music we’ve made and how really disorganized the group really is, the singer and bassist argue all the time and the drummer and singer try to get me on their side to push them down and not let them have an opinion. I’m not really good at getting social cues and fully understanding hints but I do know that they talk shit about me all the time and the singer keeps joking about me getting kicked out of the band any chance he gets and it makes it hard on my end to actually go through with it and leave them because we actually have been through a lot as a group and there are good moments with us but the way things are going they may leave me behind anyway. What should I do?
