I am in desperate need of support

Ok I am really going to pour my heart out here. Here goes. I am an emotional eater and I know it. I have really tried to control it and have been doing some what of a good job at controlling it but with the latest devastating news I don't know if I can do it all and not turn to food to help me deal with my feelings. We just found out last week that my husband's grandmother has cancer. I am so upset because all of my grandparents had past away before my husband and I started dating. We have been together for 9 years and ever since day one this woman has been like my own grandmother loving me unconditionally. I am really trying to stay strong for my husband's sake because he is taking it very hard since we live so far away from all of our family and when his other grandmother passed away last year we could not make it to the funeral. We have decided to go back and visit this coming week so that we will get to be with her when she is still herself. I could not imagine nor would I want to when she gets really sick. It has taken me way too long to realize that our family as well as our own health is the most important things in life and that everything else will just have to take a back seat. I haven't even really had time to grieve. I have been too busy trying to work out my schedule, my husband's schedule, making travel arrangements, etc. etc. etc. It feels good getting it off my chest, now all I need is a good cry and I will be good for a while I hope.
