Dawn, it's good to hear from you, even if all the news isn't good. You're still here, your docs have identified the problems and dealt with them from the sound of things, and that's the key. These RNY to DS revisions are tough and high risk, even when done in 2 stages.
So sip and walk and don't push yourself too hard til you're feeling better. You will get through this, it will just take longer than you would have liked.
