What you are feeling and what you are describing is the withdrawal we all went through-- the physical effects, the crying, the uncertainty, the self-doubt, the anxiety, the depression, and the rage. It's all part of it.
It's important that you know this isn't unusual; having said that, clearly your psychiatrist would disagree . . .
". . . if I stick it out, will I ever get over this?" The odds are well in your favour of getting off it and feeling normal when it's all done-- but it takes time, and that's the part that many find difficult. People want to know "how long?", and "will I be the same person that I was before I took the drugs?". The answer to each of these questions is totally unsatisfactory because the questions can't be answered.
The first question-- If you assign a timeline, a must-be-done-by date, you will be disappointed because it's different for everybody depending on his or her unique circumstances. Should the pre-conceived timeline arrive and you are still having symptoms it feels like a failure. Therefore, the mind state of expectation is counter-productive. You have to let it all go and just go minute-to-minute, hour-to-hour, day-to-day, week-to-week, and month-to-month-- it's like growing up: remember how when you were 14 you wanted so much to be 16? You have to forget about the passage of time and the outcome that's anticipated-- let all that go.
The second question-- "Will I be the same as I was?" The answer is, of course not-- because everything is changing every moment, and even if you'd been asleep for 2 years you'd wake up a different person-- very similar, but different. If you are awaiting the arrival of the exact same person you used to be, you will be disappointed. But yes, you will feel normal and you'll want to get on with building your life, loving, finding joy, flourishing!
This is withdrawal, and it's nasty. Even if your psychiatrist is telling the truth-- that within her set of persons withdrawing from Cymbalta, you are the first to have withdrawal issues-- she still has to take it seriously because this is new information. But there I go thinking a doctor would view the information in the light of the scientific ethic-- it's easy to forget that physicians are NOT scientists. Therefore she might not take you seriously; hopefully that isn't the case.
". . . if I stick it out . . ." If you stick it out there are no guarantees regarding the outcome; it's a commitment you simply have to undertake believing there is value in doing it. I'm better off for having stuck it out, as are many others that posted on the forum. But it's not for everybody and there's no judgement attached to that fact. You simply have to want something different than what you have and be prepared to endure some difficulty for some months until the storm subsides-- and it will subside.
Take care.
