Undiagnosed PMDD, advice/stories please

My doctors appointment is coming up but I’m very certain I have Premenstrual dysphoric disorder.

I’ve always been severely depressed, anxious, and agitated a week or so before my period. On top of the blinding cramps and lower back pain I get the day before and the day it starts, I also have intense mood swings leading up. Crying spells. Paralyzing, overwhelming thoughts. Suicidal thoughts, when it gets to its absolute worse. It’s hard to focus and complete simple tasks. I used to think I was going crazy until I read about PMDD.

I’m very open to treatment options. I’m curious if anyone has success stories with PMDD treatment. Any negative side effects from anti depressants? I feel so relieved to have finally found a name for the monthly insanity I’ve been experiencing half my life. Thanks in advance for sharing ladies
