New to this world! Mommy make over on the way!

So...just started my research 9 months ago and I can't believe that I am so close to my surgery day 1/11/12. I have been wishing for a breast reduction for years now and finally approved. Freedom at last! yayyy. I am scheduled for a reduction and full abominoplasty. I am a full figured gal at 210 lbs.  My family thinks I need weight loss surgery but all 4 Dr's that I have consulted with state that I am not a candidate.  So, I am going with their recommendation.  I am scared and not sure of what to expect out of my body. I am 5'3'' 210 lbs, 38-40 E chest and size 14-16.  My doctor states that I will be so re-leaved and that my back pain and discomfort will go away.  Has anyone had extreme results? Is it truly  worth it? I know that I will not be 114 lbs like I was pre-pregnancy but I want to feel like I can breath again...that my chest isn't my identity.......Anyone have any input or words of encouragement?      Thanks!
