I'm also new here, and diagnosed as bipolar I. I also take Lamictal as well as Celexa and the occasional Xanax. Fortunately, I was able to find a combination that worked for me, as many other meds didn't!
I struggle with my diagnosis as well. I keep thinking that I can just "turn it off" - which is of course not true! When symptoms go away, it is tempting to go off meds. I would love to go off! But I cycle so quickly that I don't think it will ever be a possibility for me.
Perhaps the schedule and constant activity of work is a positive force for you, especially when it comes to anxiety. I have anxiety as well, but I'm also a high school teacher! I deal with hundreds of people every day, and do just fine. But left to my own devices, I struggle. Not sure why. But I think that is an attribute of mood disorders, especially bipolar - we tend to struggle with routines unless they are defined by someone else.
Check out the NIMH website. They have great info. Also, some books that I've found really helpful are Kay Redfield Jamison's An Unquiet Mind and Peter Whybrow's A Mood Apart.
Good luck. And remember - the diagnosis doesn't matter so much as you, the individual, getting the help and support you need.
