Hello,
What your feeling is so normal, I had my bypass almost a year ago and not long after surgery i can remember being out with my family and crying cos they were eating and I couldn;t have a bacon bap...thinking back I feel quite silly now, depression is normal my love and you will overcome it....as someone said, depression after general is normal, but also coming to terms with such a major operation that changes our lives can cause this too....you will get used to things, it just takes time.
As for slow weightloss, surgeons and dieticians sometimes forget to inform patients that it is normal for weightloss to stop in early weeks...this is due to our bodies going into shock at the loss of food, the body thinks it is not going to get any more and so holds on to your fat stores...once it realises its getting food weight will begin to come off...it happened to me and happens to alot of people, but hey....I lost 8st in 6 months so please try not to worry. As for feeling tired, come on!!!! you have just had major surgery, your not eating much food at the moment so energy intake is low, if you feel the same in a few weeks then I would suggest going to the GP and requesting a b12 jab, but energy levels will increase in time...just give your body a chance.
If I can help any further then just let me know.
