I am prescribed diazepam (Valium) for anxiety disorder. After trying many "maintenance" meds, mood stabilizers, and depression meds I stuck with this b/c it worked the best with no long term addictions. I would get on one and then suffer withdraw or "discontinuance syndrome" as it's called in the industry.
I agree whole heartedly that there are times when you must use them if you need them. Also with Foschi (sorry don't know your real name): use only when you need them and you can avoid addiction. There will be times when it is daily, but try to back off as soon as you can for a few days.
Another thing you should check into is FMLA (Family Medical Leave Act) which covers mental disabilities and can help protect your job. It is invaluable for appointments with psychs or docs and/or those days when you just can't cope. There are conditions, but it is something you really should check into.
Hang in there. The most important thing is to just KEEP GOING. It sounds like you know this already so half your battle is already fought.
