I recently visited my GP to seek help following an unsuccessful time with sertraline medication for depression and anxiety. However I felt no different on the medication. Confused, I researched into bipolar because I felt I was experiencing similar symptoms with my uncontrollable mood swings and behaviour.

After reading more into mental conditions on the internet I now think I have BPD instead due to my more frequent moodswings which is more consistent with this disease

Have any of you guys been misdiagnosed in the past with bipolar or another condition you did not have? Or thought you may have had?  

Also, people with BPD, how helpful have you found treatment and therapy for BPD?

Thanks
