A lot of health and other mental health conditions can minic bipolar. For example, thyroid issues can cause mood swings, and Borderline Personality Disorder has very similar symptoms. So it's really hard to say one way or another.

I think you should definitely bring this up to your doctor or psychiatrist (if you have one). Or you can even talk it out with a therapist. I started with a therapist first and it helped a lot.

But obviously we can't diagnose you.

Sorry you're struggling though. I hope you get the help you need and deserve
