Melatonin horror story

I am beyond frustrated. I was taking gravol nighttime melatonin and I noticed immediately I started to feel wired I no longer got the sleep cues anymore like that sleepy feeling, I have gained over 10 pounds (still gaining rapidly) my skin broke out, my hair is falling out, and my digestion is horrible. I have never taken sleep meds in the past so I understand it might be a shock to my body but this is making me feel horrible. My sleep is much worse now and Im even losing hunger cues, thirst cues, and genuinely feel no emotion? I understand it sounds dramatic but I was fine before taking this and stopping it has had no effect Im still feeling this after discontinuing it for over a week. Can I get my sleep drive and quality of sleep back? I think it really affected my hormones as my body isn't used to ever taking supplements or medication.
