Help me with medication I got off

Hello everyone, I was taking lithium for maybe 2-4 months or so. I recently just stopped taking them problem been off for maybe 2-3 weeks. I didn't wing myself off I was taking 2 pills a day 300mg. I winged myself off like the doctor said only took 1 pill a day for like a week in a half and then stopped.

My concern I am having is I can't get horny for anything like not even a ting of anything, I having a hard time eating, having to take a appetite booster.

I need help how can I get my hornyness about and my libido and how can I start eating again? I am in need for help because it's going on a long time since my hubby and I have had some sexual time.
