I get bored sooner than later

And I'm worried my fairly quick lack of interest is going to affect my job. I'm bipolar 1 and borderline I haven't been on meds in over a year. I do get manic and do impulsive things but it's mild and doesn't affect my life negatively. But I'm worried cause I'm getting urges like I wanna cut my wrists to feel something more than just everyday or run away and not go back to work just to feel that sense of freedom. I'm totally under stimulated and I'm scared I'll do something crazy, that I can't turn back from.. And if I don't do something that will spike my interest I'll get depressed
