Feeling depressed due to working nights and not enjoying my job and having no time to do my hobbies , suicidal thoughts?

I hope you are not: feeling suicidal due to dislike of night shift and your job. I doubt that alone would lead to thoughts of suicide. If you haven't seen a medical provider to rule out depression that is a must. I rceommend aggressive treatment of depression. If you are thinking about acting on thoughts of killing yourself - please get immediate help from your nearest emergency room.
