Please help, I'm so scared.

Please help, I'm so scared. I only took a few sips. I’ve been taking Buspar for several months now, but it doesn’t help. I’ve read all the threads about this medication. They prescribed me liquid Lexapro. I dropped 1 drop, which is 1 mg, into a cup of water and drank only a few sips. But I’m crying from fear; I’m so scared of the side effects. How can I return to normal life without this medication? I’ve been afraid of nausea since childhood. I’ve never smoked or drunk because I’ve always been afraid of side effects. I’m so scared, I’m crying. I’m afraid of all medications, but this one the most. What should I do?
