He laughs at me when I get irritated when I am trying to help him.
My husband is in remission from cancer Prostate cancer that mets to his right sacrum. But he is having spinal issues, radiculopathy, spinal stenosis and severe arthritis in spine which has him on Morphine and percocet. He is basically home by him self, still weak on his feet, we walk when I can get him to.
Given your husband's condition and prognosis and the inability to continue to lead a normal life. You say he is alone much of the day which I assume means that your are both younger and you have to have the income. Is he still able to drive? are there places he would like to do and activities he might enjoy. He sounds too young for adult day care but are there people he could go fishing with for example, or if he is competitive maybe join a bowling league. If he has a favorite hobby can it be miniturized so he can . One gentleman I knew was able for many months continue to go to the local coffee shop and continue to hang out with his buddys. I am not unsympathetic to your frustration but you have to be the one to begin taking the lead and just making decisions.
Please PLEASE don't take it personally. Just try to understand that your husband is in a fight for his life. Support him in whatever way he's comfortable -- and love him to bits and pieces.
Schizophrenia?
The laughing behavior is also a symptom of smoking pot, as well as excessive hunger, or having the munchies.
No matter the cause, if someone is constantly laughing at you, that is a sign of disrespect, just like when you speak and they roll their eyes as if to say, what you say, think, or believe is irrelevant and stupid. Walk away.
That being said, I think that your husband has an awful lot going on in his life and that there would be very little to laugh about. I would be turning cartwheels if I thought I could get him to laugh at me.
However, your question was, is it normal to get frustrated and irritated at your husband. A very resounding YES! You would have to be a saint if you didn't occasionally get frustrated. Maybe you are a sainte anyway. Make him laugh, laughter is the best medicine. Be sure you laugh with him!
Sig other also takes Percocet for his back, but this annoying frustrating laughing has been his trademark for decades according to his grown children.
