My husband was diagnosed with bipolar 18 moths ago at the age of 67. As well as this he has end stage copd and spinal stenosis so things he can do are very limited. About every 6 weeks he goes from this poorly man who needs everything done for him to this nasty argumentative person. I really struggle with things at this time as I don't know whether it's bipolar setting off or whether meds need changing. I would really appreciate any advice please.
