I think meds can help with a lot of the symptoms but not fix every aspect of it. The mood swings can be helped with mood stabilizers definitely. I've never been diagnosed with BPD, but I think I have/had it but it's under better control. I still struggle with impulsiveness.

For example I a little over a week ago. If I used some sort of coping strategy to get through that moment I may not have done what I did. I had the same thoughts yesterday when I was very overwhelmed but I made the decision NOT to take that action this time.

I think the best thing for mental illness is a combo of meds and therapy with a good support system.
