Thanks for using healthcare magic,
I have gone through your history.
You should have taken psychiatrist
for detailed evaluation and proper dosage adjustment. You should not do it on yourself.
Your psychiatrist will decide whether you require further medicines or not and if not, how to reduce it or omit it.
Sudden stoppage of Anti depressant
drugs after use of these many years may cause withdrawal features which are usually temporary in nature. But in some case it may last longer.
Meanwhile you can do stress management
and yoga for better control over depression
