As somebody who has also suffered from fatigue very heavily and also played sport and fitness I know how hard it can be. When you say you feel so tired most of the day I can totally relate to this as I suffered like that for many years and still do a little now. I was so confused so much of the time as I din’t have a clue why it was happening and doctors just kept telling me it was because I must be depressed.
Last year I changed my diet and miraculous things happened which proved the doctors wrong however, have not managed to keep it that way. I still haven’t completely worked it all out yet, can’t be 100% that I actually have candida but I know that it has something do with food and/or digestion, the gut is a very complicated maze. What I have done since about a year ago is keep studying about the gut and just learning as much as I can, that’s the only thing has has kept me going. As I say the gut is a very complicated area and it’s why doctors come up with IBS, it’s just a way of telling patients that they don’t know what’s wrong with them.
Keep going, I know it’s not easy to do but try to keep mentally strong through it. I would study as much as you can and get a much more rounded view. Study about the gut area in general, about diet and anything related. I know that sounds obvious and you may already be doing this but it’s really important as you will find something new that you din’t know and can be just what your looking for. You might just read something that makes something click or a lightbulb moment happen that may at times even contradict a medical specialist which has happened for me a few times. It’s fast becoming the case that a lot of people can actually help themselves better than health services can.
I can’t really give you any specific advice other than what I’ve said but you should always be careful when eliminating lots of foods. It can be very dangerous as you may not be getting vital nutrients and vitamins even if you’ve been advised to in some cases. I am speaking from experience with that as well.
I’m definitely no expert but I know there’s at least a couple of people on here who are close and have some very useful advice from what I’ve read on the forum. I’ve done searches for die-off symptoms and found some very good posts to other questions so maybe you could try and do some searching. This place is a great resource!
Really sorry I can’t help you further – but keep going & Goodluck!
