Hi EBB,
I am so sorry to hear about what you are going through. What you are experiencing is, unfortunately, very familiar to many on this site. I know that doesn't make the fear and anxiety any easier but anxiety is a liar. it will get better. a good sign that you're not going crazy is when you actually have the self awareness to wonder if you are ;-). recovery can be slow and for many the process was 2 steps forward and 1 step back. some days its 2 steps forward and 3 steps back but slowly over time you will be able to see you are making progress. journaling/blogging - even tracking your posts here over a period of months - can give you a better idea of how much you've improved.
to respond to your most recent question, frequent urination is a major symptom of anxiety - infection not needed.
however, cymbalta does cause an increased susceptibility to UTIs. that is a common side effect of ssris and ssnris - as they can act as a vascular constrictor. that's why high blood pressure is often a side effect of anti-depressants. the C makes it difficult to empty your bladder all at once, so when you think you're done, you're not. you end up going more, and you become more susceptible to infection when unable to void completely. because of that impact, duloxetine is actually prescribed outside the US for urinary stress incontinence for women under the brand name Yentreve. so depending on what ails ya, what is a curse for some is relief for others. UTIs were a major reason i decided to wean off cymbalta. i've been off for four years now and UTIs are a rare occurrence anymore.
there is no magic bullet or quick fix to treat withdrawal symptoms. for the anxiety i highly recommend therapy with a licensed mental health counselor who is trained in cognitive behavioral therapy - CBT. they can help you develop ways to recognize the negative thought processes that perpetuate the cycle of anxiety and help you develop skills to challenge those things we tell ourselves that leads to catastrophic thinking. i took the C for depression but never suffered from chronic anxiety until i started weaning off - it developed into full blown GAD. for awhile i took clonidine but no longer. anxiety remains low level for me but is very manageable - its taken a lot of work. i went cold turkey from 15 mg/day and it was very difficult. i admire all those here who've managed to raise children while in withdrawal. i cannot imagine.
i am not on the boards nearly as much as i used to be but i poke my head in from time to time when i get a chance to share what i can when i can. you won't find a better support system than the folks here.
