Pmdd for 3 weeks and 5 days due to missed period

I don't know what to do at this point.. the entire month feels like a foggy mess of memories..

I'm in so much pain- all my muscles ache, the anxiety has turned into health paranoia, I haven't slept well in so long.. I'm constantly depressed. my skin tingles when I touch it.. my head swims when I'm awake for 12 hours..

having pmdd for this long makes me feel like I'm dying.. physically and emotionally.. I just don't know what to do anymore..

and no I'm not pregnant, I'm asexual.

so I'm asking for advice here because my last post 4 days ago i didn't ask for any.. but now I feel desperate..

I'm so desperate for help.
