I started taking lexapro 20mg about 2 years ago. I stopped taking it 4 days ago because I dont have the money to get it. For the last 3 days I am having severe withdrawel symptoms; chills, sweats, crying spells, anxiety, dixxiness, extreme fatigue, headache, jolting electric senstation, tremors, agitation, irritability, aggression, nightmares, blurred vision, vertigo, confusion, concentration difficulties, weakness, and my brain feels like it it squeezing itself every five minutes. I am really scared cause I have never felt this way. I feel like death. I am literally craving my lexapro. I dont know what to do. Should I go to the hospital?
