What's your tapering schedule, and why aren't you doing this in concert with your psychiatrist? At any rate, the taper should be as slow as you need to go -- you've been on this a long time, and of course, as you know now, should never have been put on such a drug at such a young age. So in essence your brain has developed along with this drug, and it might be very hard for it to operate without the help of such a drug, if not this exact one. Only time will tell that, and that can also happen to people who started as adults -- it's one of the lesser publicized downsides to taking these meds. That's why the slow taper -- to give your brain the time it needs to adapt back to working naturally, which means dormant serotonin receptors have to awaken and function. You might pick up a book called The Anti-Depressant Solution, which discusses how to come off these drugs.
I haven't yet consulted with a psychiatrist because I am still living at home and my mom is pretty adamant about me remaining on medication, especially since I am living at home and a withdrawal could affect the whole family. But I also do not want to let her fears dictate my decisions as I have done for the entirety of my life.
