Jennifer,
YOU ARE NOT a failure girl. We all have humps in life. Don't beat yourself up. You are doing the right thing moving forward! I am a gastric sleeve patient, but I also paid cash. I opened up a special credit card account they offered with no interest for 16 mos. I don't know what your financial situation is, but this is an option. Good Luck Sweetie
I had my sleeve Jan 10, and I have had similar problems. Feeling weak and my blood sugar has been a little wacky and I never have had diabetes. Hang in there, it get's better with time my friend. I too have oxygen for awhile at home. I have found my-self just wanting to lie down on the couch but have made my self get up and get moving which has helped. What a journey...Keep positive
