Dealing with PMDD

Illiana
Anyone else have it & know how to cope with it, it overwhelms me to the point where I wanna hurt myself. First comes the negative thoughts then the emptiness and sadness and eventually I'll get angry and more sad.  I've been feeling it for the past couple of days again because of course my period is coming its just really hard because I have depression and general anxiety and I was doing so well getting back on track and everytime during 10 days before my Period this happens. I end up stressing my boyfriend out and everyone else around me but mostly him because I talk to him. Please if anyone knows how to help with advice please do !
