I feel really weak. I tried to take a walk but it was really short, and felt really weak. Is physical weakness a side effect of starting lexapro, or is it the depression? Or something else? I'm worried. Should I go to the hospital to get myself checked out? It's my second day on 15mg. Yesterday was terrible, with lots of anxiety and overall sickness and weakness. And today I feel my body is very weak. I tend to have physical symptoms with depression so i'm not sure if it's the meds or not, but I'm starting to get worried. Do you guys feel general weakness when depressed?
