Call the Dr. If he keeps this up he will end up in the hospital again. You mention that he takes lots of depression meds. Could any of these be causing adverse reactions to his other meds? Do you know that he is taking anything properly? In his state of mind he may be forgetting to take something or taking too much. If he is not taking the depression meds this could cause some mental issues, you usually need to taper off these. It may be time for you and your kids to buck up and take control of his medication. None of this is normal. At any rate, a doctor call is in order. Hugs.
