I am so sorry to hear about this. My condolences. I went through the same thing. My co-founder was also in the "I'll give you a kidney" category. OP is right; something like this really puts things into perspective. In my case, I decided not to continue for 2 reasons. First, there was too much work for one person (there was too much work for 2 people). But more importantly, I just didn't care anymore. I ended up taking a job and it was a quite a while before the passion returned. Respect to OP for making the decision to continue. Greg is with you, even if in spirit only. Please succeed for those of us who didn't.
