Can derealization/depersonalization be a ssri withdrawal symptom?

Possibly: Stopping an SSRI can be very challenging for some and it is very important to have close monitoring by a doctor of any symptoms that develop. It needs to be done slowly and each person's characteristics can make a difference. It's worth doing but it must be done carefully. Don't try to handle it alone - you want the doctor to be responsible for these decisions. Glad you're better now!
