I had no idea, not an inkling. When I was 15 and feeling quite unstable, my mom convinced me that I was just overly sensitive and melodramatic. She also said I wasn't good at handling life
10yrs later I was dxd and had my 'aha moment'. I didn't doubt it, coz it just made so much sense, and also validated all those times I was struggling but didn't know why.
I am however currently unmedicated by choice, and would only go back on meds if my dx ever changed from type 2 to 1...
