I'll tell you my experience. I think that, if you have issues, chances are if you don't have bipolar you have something else in any case. I don't think it's possible to have problems like those without having a mental illness of sorts.

Thing is, if you don't have bipolar but still have a mental issue, you wouldn't have any problems from taking antipsychotics. I have been misdiagnosed with bipolar for 10 years, when I found out I had BPD instead. I still take antipsychotics, so my meds have not changed that much.
