I used to be prescribed medication for it

It takes a lot of time and self-investment. Dealing with it works differently for everyone, but I would start with getting stable with a mental health "toolkit" by building coping skills. Then you can works towards really understanding the disorder, how it works, and where it may have come from for you. You can eventually be asymptomatic!

Myself I have been in Dbt to help I try to read up on it accept my emotion and my failures or mistakes Ive made constantly through my life and currently I am trying to figure out exactly what self love is and how to use it.

Weekly Schema therapy

I use a mood tracking app...it helps me see when my moods are out of hand....the one I use is easy and simple to use so you're not expected to write out alot on how you feel

Therapy helps too
