Lexapro withdrawals/ Pregnancy

I stopped taking my Lexapro about a week ago and I feel so sick and nauseous. I’m having a very hard time being a good mother to my toddler. I also have restless legs and I’m not sleeping well at night. I was on 20 mg for about 7 years. We decided to start trying for baby #2, so I had about 6 months to taper off. I went from 5 mg to 0 mg, and I know a lot of people recommend tapering from 2.5 mg instead.
I stayed on 10 mg of Lexapro during my first pregnancy. I know it’s unlikely, but I can’t help wondering if it could have contributed to my daughter’s heart condition, and that fear has definitely been part of my decision to come off of it.
Does anyone have any success stories or words of encouragement? Did things start improving after the first week or two? Every time I search online, I seem to find nothing but horror stories. 😂 The thought of being this sick combined with the first trimester of pregnancy seems unbearable to think about.
