3x/week is an ideal schedule for getting this goal done, so good job on that! When I was leading C25K classes, I said in the pre-class materials that the hardest part of C25K for most people is carving out non-negotiable running time. ("Treat it like you have to pick up your kids.")

My sympathies about the emotional stress. That is not a light burden, and that's why I was offering to help and/or suggesting a coach. Ideal would be a run buddy, but I'm in Somerville, so I don't think I'm anywhere close, because from the sound of it, what you need is a "show up, and then I'll do the plan. In fact, I don't even need to know what the plan is; I'll just do it" mental effort-less help for awhile.
