First off, I have been diagnosed with bipolar disorder since I was 18. It was a bitter pill to swallow and it took awhile to adjust to the diagnosis and get my medications in order. However, I have been fairly euthymic for several years now except for a few instances and just graduated from nursing school, passed the NCLEX, and got my first job at a state psychiatric hospital. During training it was all day shift, but now that I am officially working the floor I am finding it difficult to work a rotating shift. I rotate from AM's to PM's with mostly PM shifts with the possibility of being forced to work the next shift. This was not exactly what I signed up for. I can't regulate my sleep schedule and my moods are all over the place. Even when I worked a straight week of PM's I fell into a deep depression complete with suicide ideation and a suicide attempt that thankfully did not end up with me in a locked unit but just the emergency room. I am still on probation for 6 months but it is becoming increasingly obvious that PM shifts just do not work for me. It just increases my anxiety and depression so much. I like my job and would like to keep it especially since the benefits and pay are great but i think I need a steady AM shift to function. Is this weird or unheard of? How would I go about this with HR? I am not sure I want to disclose my mental illness to them.
