Patient discussion about blackoutQ. What does depression cause? and how can i get out of the black hole i got my self into ...? A. What does it cause: a loss of interest in things that were previously routine, withdrawal for social situations, withdrawal from friends and family, avoiding confrontations, avoiding stressful situations, diffuculty making decisions, feelings of deep despair and sadness, unhealthy guilt. The list does not end there. How do I get out of this hole: See your medical doctor for evaluation and followup routinely. Take your medication on time everyday. Be patient with yourself. Try to let go of unneccessary guilt, or resentments and anger from past experiences. Forgive others who may have hurt you. Forgive them from your heart. Try to make amends to others you may have hurt. Take time in your day to reflect on things and try to resolve to do better. Don't give up. If you fall down, get back up and go at it again. A good nights sleep is very beneficial. So is exercise or physical activity. Walking is very good. Q. Does anyone have information on Bipolar "blackouts" or know what they're really called? My boyfriend is bipolar and experienced a blackout a few weeks ago during which he did something completely out of character. A crime was committed and he has since been arrested. He's having trouble coping as he has no memory of the crime. He was on Wellbuterin and a doctor prescribed steroids and vicodin for a crushed disc. The chemicals may have led him into this blackout. He is a wonderful loving person and is now facing a life sentence for this terrible thing that happened that he had no conscious control over. They will not continue his medications in jail and he is not receiving mental or medical treatment. Is there anyone out there that can help me find some answers? A. i never heard of such thing. but there are strange results sometimes from mixing drugs that affect the central nervous system. here is for instance a web page talking about interactions between Vicodin and Wellbutrin. http://www.drugs.com/drug_interactions.php
