Welcome to HCM
contains escitalopram. It is a SSRI
drug and it is a very nice antidepressant medicine. You were taking it 20 mg per day and later 10 mg per day. You have complaints of negative thoughts, low confidence, headache. These are the features of depression
only. Headache may be a somatic manifestation of depression. So when you stop the drug symptoms reoccurs. If you want to get proper relief I would advise you to please visit a good Psychiatrist
for expert opinion. Don't try to stop medicine by your own.
