In your case it just sounds like you never solved your problem. In my case, I got stuff I never had, and I was in my fifties so I pretty much knew what my problems were. If you just get the same problem you had before you went on meds then you just haven't solved the problem through therapy or some other way and the problem is still there, so the need for the meds is still there.
I've been treated with anxiety and antidepressant since 2001. I've tried o get off of them several times. Unfortunately, my live would go to crap again, and I had to go back on it. The one thing my doctor did with my Zoloft was to give it a side kick with Wellbutrin. It's helped my focus skills emensely.
As for what you worry about...well, it's a crazy world and I honestly think you and I are OK, but most of the people out there have lost their bloody minds.
Hang in there
Yep. This is a common withdrawal symptom. The reason you don't hear about it as much as you would expect is because psychiatrists and doctors will tell you it's a new problem, not one caused by withdrawal. To find the truth, and I know this because I went through a much worse fate than yours with this drug. you have to look at the work of addiction researchers. Antidepressants aren't classified as addictive drugs, but if you google protracted withdrawals you will find more information. You will also notice that most people who go on these meds seldom are able to stay off of them for the rest of their lives if they take them for an extended period of time. That's because, for many people, their brains are not able to adapt back to working naturally. It's even worse with benzos. Now, this is still better than suffering forever with intractable anxiety or depression that therapy is not able to help, but it's a problem docs don't warn us about because it would interfere with their income. I know that's crass, but it's unfortunately true. Look at how many people just on this site go to their docs and are not sent to therapy first to at least see if they can get better without meds but are instead put on these drugs, often for problems that aren't chronic or even mental in nature. I was an extreme case, and I don't expect you to become one -- my withdrawal has never ended and never will. But I didn't know about the possibility of withdrawal because nobody ever told me, but you do know. What I would do is slow down the taper -- I know, it's been a long time, but go even slower. If no length of taper works then you just might have to spend the rest of your life on Paxil -- many people have done just that. But if you take it really slowly and calmly, knowing what you're facing (I didn't), and make your lifestyle as healthy and optimistic as you possibly can knowing your situation (as I didn't), I believe your brain can get past this with a little nudge by you. Good luck.
