I have had depression
for 20 years, and know I must stay on medication
for the rest of my life. I am 69 so not so bad, for a younger person it must be a worry. Obviously you have to stay on an anti-depressant until you feel you are well enough to stop.
I have stopped 3 times, but for me, the depression always comes back. You have to decide what is best for you. It is known that depression does often return. Try stopping, if you feel you want to, and see how you go. Only you can decide.
