Holly,
You are TOTALLY doing the right thing!!! Imagine if you did not have this surgery - which is saving your life - what you and your daughter would be going through over the next few years. None of us are getting any younger - and with this condition (and the comorbidites that come along with it) you/we are drowning and sinking more every day. You are saving your life. You are ensuring that you will have a future with your daughter. As a parent, the focus shifts between ourselves and our children. Imagine your daughter's next few years if you were not to have this surgery. Would she have an active mom? Would you be able to keep up with her? You will regret not being able to do so many things with her if you are too large and uncomfortable to get around :(
Keep fighting and don't give up! You deserve this new life and so does your daughter!! I assume your brother is scared and does not have all the facts. Chances of fatality during this surgery are miniscule (sp). Maybe you can send him some information that will help him understand exactly what will happen. If it doesn't help - then just know that you have nearly 95,000 supports right here (AMOS).
Love, Crystal
