Hello singular: I'm sorry I don't think there is much of anything I can offer in the way of advice here. However I noticed this is your first post here on PC. So... to PsychCentral! Hopefully coming here to PC can be of some comfort & support.

In the meantime, here are links to some articles from the PsychCentral archives on how to survive a divorce. Perhaps something in them will be of some benefit:

Also, with regard to your leukemia diagnosis, PsychCentral has a sister website... "NeuroTalk". The members there have a lot of first-hand knowledge with regard to a variety of physiological / medical conditions. So, depending on how things are going for you in terms of your medical concerns, you might wish to take a look at the NT forums as well:

I wish you well...
