I’ve experienced 1st and 2nd hand relationships with bipolar people. My ex took some different medications for it and ended up having some pretty severe effects which don’t sound at all like what you’re taking. (I wish I remember for sure what meds those were, because I’d stay away from those.) I know that it can pose some challenging experiences around ego. I remember her saying she felt like she’d lost touch with her sense of who she was, and it was rough being in relationship with her – she was sometimes quite positive and full of (somewhat obsessive) energy, or really negative and/or aggressive in a wide variety of ways. I know a relative of mine who it seems to me has many quite similar patterns to hers, and one thing they both have in common is very swingy diet habits that often seem to cause the mood swings. Such as not eating much for a while, and then binging on carbs, and then going nuts after the carb binge. Oh these people are also both somewhat paranoid schyzophrenic and have some other issues, and everyone’s different, so I don’t know how much overlap there would be. I think finding a trusted strong professional counsellor would help both of them (again, I obviously don’t know you or how much of the issues I know about them are related to bipolar disorder), but they have been really unlikely to trust any such person. They do both seem to get a lot out of good supportive friends, but for the people I know (more due to the paranoia than the bipolar, I would say) keeping supportive friends was challenging. Best wishes!
