I have also been diagnosed with bipolar disorder. After being diagnosed I was put on medication. It is defiantly a sneaky little disease (in my case anyway). I will slowly start coming down (or up), think I'll be okay, i think "it's not that bad...." and the next thing i know im out of control. I HIGHLY recommend that as soon as you start noticing your mood changing to call your psychiatrist ASAP and let him know.By getting it under control fast, you'll more than likely be able to avoid an episode. If you are not on medication, i highly recommend finding a psychiatrist. It can be a long hard road to find the right combination of meds but it is more than worth it. In relation to applying to nursing school, I didn't and dont recommend letting anyone know unless asked up front. We had to get a physical before starting and when asked about my meds i did let the doctor know. Unless necessary, I wouldnt tell anyone at school, or employer know. I hope this helps and just know that it is totally possible to keep your disorder under control and never sell yourself short or think you cant do something because of your disorder. :]
