Dizzy

I’ve been so super dizzy, I’m afraid to even stand up. I’m five weeks pregnant and my doctor said it would be best if I stopped taking my antidepressant. She said the side effects should be minimal. I don’t know why she said that. I just looked it up and everyone trying to come off of lexepro has terrible withdrawal. Everything I’ve read says it’s best to taper off over a few months time. I don’t want to take it at all if it might hurt the baby, but I don’t know what to do about the dizziness. And I can’t call the dr cause no one ever answers the phone, and I can’t switch doctors until next month when my insurance starts at work. Any tips on how to deal with extreme vertigo?
