Hi there! As a caregiver and a social worker I totally understand where you are coming from! Try to hire a caregiver, sometimes the state will help you out with this, you need a break! It is tooo difficult for family to take care of family members under these types of situations(just my opinion)!
As a caregiver I have learned when to walk away, as I get frustrated too,
especially when they are not motivated, my saying is that "you can lead a horse to water, but you can not make them drink".
You might want to think about hiring an experienced caregiver even if it is just a couple of days a week, just so you can have a break! I wish you were here so I could help you out!
I do understand pain, I live in pain all the time, but there are tooo many people out there that take it out on the wrong people!
I agree with pattyv, he does need both a neuro and a pain management Dr., and possibly a psych eval., but most men are in denial about this(the psych) you might want to talk with his Dr. And let him/her know what is going on.
Sincerely,
sandy
