Ask if there is any respite care available. Caregivers do get burned out, and when you have your own problems to deal with yourself, and his on top of it, that would be really rough. I could see the pair of you, both needing help, engaging in behaviors that might get progressively worse, almost competitively (even not meaning to be so intentionally) as each of you tries unsuccessfully to get the help that you need. Please ask for help from someone who is in a position to help you and/or help you find the kind of help that you need.
