Advice please!

Hello, i am young (below 18) and I think i have pmdd. Before I get period I suffer alot mentally to the point of suicidal ideation and intense depression and anxiety. it's like suddenly I think about everything bad that ever happened and can't stop thinking about it. During my period I might be a little sad or have a bit of anxiety but other than that I get some relief then I realize "Hey I wasn't crazy it was just my period".

 I feel like the only relief I really have is during my period and right after because even ovulation is a mess mentally for me. I'm just really sick of feeling like this and each mental spell I feel like it getting harder to pick myself back up, but because of my age and circumstances I can be medicated right now. So any advice on things I can do at home to ease symptoms of this? Thank a lot! My first post got taken down 😔 and this isn't really a rant link the flair says but I had to put a flair 😭
