I am so sorry you are feeling this way. You are NOT irrelevant. Your wife needs you more than you realize. You sound like you are dealing with many stressors at the moment, which can really aggravate the pain and dampen our optimism. Sometimes the medications we take for RSD can also contribute to feelings of hopelessness and despair (I know after I started taking Lyrica I went into a severe depression; many of these meds have black-box warning labels on them now). Please talk to a professional about how you are feeling. And this may sound ridiculous, but is it possible for you to take your wife on a vacation somewhere warm for a bit? I thought I read in another post that you're from MN? I live there, too, and this has been the worst winter that I can remember in a long time.
