PMDD support

Im not sure how to start seeking support. The two weeks before my period are absolutely crippling. I can't leave the house, my anxiety is so intense that i feel like I'm constantly on the verge of a panic attack, my whole body trembles and breathing is difficult. I get headaches, horrible insomnia, an overall sense of doom and despair and feel.like i just want to end everything. I can'tthinkclearly andverything makesme cry. -- i don't think thesearejust standard pms symptoms?
