Why do i feel so sick?

Ive been feeling off lately. Im talking nauseated, headaches everyday this month, super tired, cramps. All that fun stuff. I bled for about 3 days way lighter than usual which made me think it was implantation bleeding? But heres the thing, i havent had sex period for about 3 weeks and ive had my period since then so theres no way im pregnant . So ik its not that. I have bad anxiety and last night i had an anxiety attack and right away i started breaking out. Maybe its anxiety? Idk helpppp

Edit: ive also been having A LOT of cream colored discharge. More than normal
