My husband

For more than a year, my husband has been experiencing what I would describe as a mental breakdown. He has not worked since then, and we may lose our home. Most days, he spends all his time in the recliner; however, over the past two days, he has been up all night. 

While he has been engaging in activities that I would like to think are positive, his lack of sleep concerns me. 

Is he experiencing mania again? Should I wait and see how he manages? This behavior has led to him being hospitalized five times this year due to suicidal thoughts.
