Lexapro side effects, please help...

I'm having a difficult time getting my Lexapro filled, it's been almost a week of back and forth with my pharmacy and doctor playing hot potato and I woke up today feeling so sick. I'm dizzy, nauseous, can't stop crying. Is there anything I can do to ease the side effects?? Anything I can take, eat, drink? Doctor says I should have something today but I'm so sick idk how I'm even going to go get it. 😭 Anyone else been through this
