First...
I lost my dad to colon cancer in 1997.
That said...when I first started my weight loss journey on September 6, 2010, my health was starting to fail (high cholesterol, blood pressure, etc.). I was doing soooo great with my new way of eating and then on October 22, 2010, my brother died unexpectedly. It was tragic.
Absolutely earth shattering for me. It actually felt worse than when my dad died, because I knew he was dying for 18 months...my brother was only 10 yrs older than me and looked in GREAT SHAPE.
I totally understand what you mean about feeling bad to even be thinking about your weight. I felt exactly the same way. At first I felt like "nothing matters anyway...certainly not food, I could be dead tomorrow like my brother" and just plain "guilty" for even thinking about myself.
But then I decided to channel those "negative" thoughts into positive ones. I decided to become ULTRA focused on my health, realizing just how uncertain and short life can be. I decided to show more appreciation for this GIFT of life and realize that it is, in fact, a GIFT and not a GIVEN.
So, I started to RUN. It was the best thing I ever did. Can't really describe to you how it helped me to cope with all those extreme feelings of sadness...but it did. It really did!
Death/sickness can make a person feel so helpless. To overcome that feeling of complete and utter helplessness...I focused on the fact that I can EFFECT my life, and very possibly how long I live....but most certainly I can effect the QUALITY of my life.
So...while every situation is difference, and we all have different methods of coping with stress...this method was both helpful (kept me busy and my mind focused on something other than grief), and positive for my health (my blood pressure, cholesterol, etc are all normal now). I look and feel great. Something good came out of something bad.
My hope is for you to cope with whatever comes your way with some kind of positive outcome for you and your loved ones. Take care.
