Marie -
I'll tell you where I am right now and maybe that will help you. I am also considering (strongly) WLS. I have two boys, ages 5 and 2. I am 5 6 and weigh 270. Morbidly obese by technical standards...but of course not by most people who know me. I'm built like my 3 brothers so I don't look as bad as some people do at this weight. It makes it harder for me to "justify" to myself that I need this surgery.
But I AM 270 pounds. (No matter what frame it's on). Right now I do not have any comorbidities...but my knees hurt, I have shortness of breath when I exert myself, I deal with depression (which I believe is strongly weight related), and in general the weight IS affecting my life. Do I deserve better? And do my kids and husband deserve better? I MIGHT die (yep, there's that chance) but I have a better chance NOW (while I am "only" 270 with no comobidities) than I do if I wait until I'm heavier or develop other problems. I deserve to play with my children and they deserve that as well. My husband deserves a cleaner house and a woman who isn't always depressed about life. I deserve to enjoy clothes shopping and going out and doing "physical" type things. I want to go on amusement park rides with my kids. Etc. etc. So I've decided to move ahead (through the fear) and I've prayed that if this is NOT what God wants that He will put an insurmountable road block in my way.
That is where I am. Maybe it helps to see another perspective? Ultimately you have to do what is right for you. Good luck in your decision.
