Definitely mention your feelings to the doctor. My period made me extremely depressed (I already had depressive episodes before) but my period made me feel suicidal . Talk to your doctor, please!
Talk to your doctor! There’s actually ssri’s that can help with pmdd!
I have PMDD and had some similar symptoms that led to my diagnosis! I did end up going on an SNRI (Effexor) because my symptoms started including SI and feeling out of control, and that has helped me so so much.
I personally would. I was similar before going on the implant and it made it SO much worse. Once the implant was fitted I was extremely suicidal. Obviously it can affect everyone differently, so you might be absolutely fine with it but I would make sure they're aware.
