I was on Prozac for 20 years. I think most of that time I was fine--and I thought I was too, just a little tired all the time, when my family practice doctor suggested I might be depressed, knowing I had a family member with schizophrenia.
That stopped working for me a year or two ago and I slipped into a deep depression, but I was functioning, so I just carried on. Didn't realize that my irritability and mood swings were symptoms of something deeper that could be treated. Then my husband left me, as he has conflict phobia and couldn't figure out how to deal with me, and had an old friend he formed a romantic relationship with. He came back after six weeks and we've been going to counseling to try to repair our relationship. I am also seeing a psychiatrist now and taking different meds--Cymbalta and Remeron. I feel so much better now, and I think it's largely the medications. I am really a pretty level-headed person most of the time and cope quite well. I held a responsible position in management before my early retirement (age 50--I was blessed!)
Had I been more knowledgeable and alert I could have sought new treatment sooner. I suspect your life will probably be largely positive. You may have some slips--it was serious adverse events that sent me pulmenting to the depths of despair. But you will probably more quickly right yourself again too. It's good that you have a husband and friends around you--those of us with support systems do best.
Do check out the symptoms of mania--some with bipolar disorder are originally diagnosed as only depressed. If you go high and low, you generally need different meds I think. If it's just the euphoria of feeling better, go ahead and celebrate!
