coming off Combined pill?

I’m 3 weeks into taking Mercilon

(thank god i only have 3 more weeks maximum to go as GP recommended, but i feel insane. My mental health is on the floor, my sex drive is non existent, my skin is breaking out, i’m nauseous every night and i’ve head a continuous headache for a week

i want to come off it. how long did it take you to adjust? how long till you went back to normal after stopping?

please help, any experience is appreciated
