Hi, my friends husband mood will all of a sudden change.  Then he gets really mean and says things to my friend anything to hurt her feelings.  It doesnt matter what it is whether she didnt cook dinner right or put her down about her son, anything to hurt her and get her going.  When he is in a good mood they get a long great and have a lot more good times than bad.  But when its bad its really bad.  He has not hit her but he is so mad she does keep her distance.  It almost sounds like a stress of something with set him off.  He seems to have this mood change once every two months or so.  She is very confused and loves him but cant be abused like this.
HI, Thanks for using Chat Doctor. I have gone through your available history. It seems that he is suffering from Depression with poor impulse control, but other illnesses like bipolar mood disorder or substance use should be ruled out. It is advisable to consult psychiatrist for detailed evaluation and management. Doctor after confirming the diagnosis, Doctor may advise treatment options like Chat Doctor. I hope He will be fine soon. Thanks.
