Don't give up, and I completely understand how you are feeling. The same has happened with me with every diet I've done. I would have weeks without any losses and it's so disheartening and I would give up and end up getting fatter and fatter. I've stuck this week and I'm determined to not let this get to me. I keep trying to think, even if the weight isn't come off as quickly as I like then surely my insides will be healthier iyswim.
You're doing well with the exercise too and this is important, don't give up. I have M.E. and am unable to do exercise and I really wish I could.
You CAN do it, you CAN do it, you CAN do it, don't give up.
