Hi lindylou
Sorry to hear about your tiredness - the CFS diagnosis sounds like it is hormonal and that your thyroid condition is not being treated properly. Added to that if you are menopausal and lacking in oestrogen, then this will undoubtedly exacerbate your tiredness. Some women also suffer from much reduced testosterone which also leads to tiredness/CFS symptoms.
I urge you to take control and look into getting the right treatment for your thyroid, HRT if you are menopausal and see how much better and less tired you can feel.
As has been said on another thread some doctors consider such diagnoses (like CFS) as a dumping ground - and to me it does women a disservice by not considering all the hormones (ie the three main ones) that can affect our state of mind/metabolism etc at the stage - and leaving women to suffer needlessly.
Have you had checked all your vitamin levels, iron etc and are you having very healthy diet and plenty of fresh food - perhpas a few well chosen supplements now and again? There is some info about health and lifestyle here:
