Hi hun, sorry you are having a rough time and getting disheartened. I'm on LT so haven't experience with CD, I am sure that others will be along to comment.
Have you discussed it with your CDC, what is she saying about it? Are you sole sourcing? If you are then it has to work if you keep at it. If not you could review all the basics, are you taking enough water, are you following 100%, are you having TOTM problems that could be impacting upon your fluid levels?
Sorry they are just the obvious things others will be better able to advise. I really believe the 'science' of LT/CD/LL so if you persevere it has to work. The trouble is it is really hard to persevere if you are not getting the good losses week to week. You should be proud of yourself for persevering, hope things come good soon x
