OCD is slowly consuming my life and making me miserable and i don’t know what to do

I have a really bad case of contamination ocd and i don’t even know why it’s this bad. I am terrified of my body being filthy in anyway especially my hands.
i’m most terrified of using the bathroom however. whenever i get the urge to piss or shit it fills me with an overwhelming sense of dread and sadness because i know that im going to waste hours of my day going in the shower and obsessively trying to scrub away the filth i feel all over myself. it’s becoming so concerning i’ve started to use antibacterial hand soap all over myself body and hair scratching really deeply in an attempt to get rid of the feeling and even then sometimes i have to wear gloves or something because i cant stand getting my hands covered in germs.
it’s just absorbing my life i have spent hours and hours just in the shower when i could be talking to friends or doing other things. it’s ridiculous. i can’t even clean my bathroom because im petrified i might accidentally get really dirty again and have to waste yet another day showering and crying.

I just don’t know what to do anymore. i know i need help but that’s it
