I am only 3 weeks post-op, so I am right there in it with you. It sounds like you have a great supportive husband, so let him support you! He probably feels a lack of control with your situation (as husbands do) and letting him care for you and your kids will make him feel better while you rest and get better too. The dishes and laundry can wait- you need to take care of you for the time being.
Being on liquids for 4 weeks will make you hungry and even agitated about the things you can't eat. I just graduated to pureed and am feeling so much more satisfied. I still LOVE food. I will love food whether I am fat or thin, sleeved or not, but now I can cook, watch cooking shows and not feel sad or angry. I can cook a great dinner for my kids and be excited for them without being sad for me. It is a transition- don't be discouraged- talk to others, share your story and listen to theirs. You will be feeling better in no time.
