Chronic fatigue syndrome??

I will start off by saying I have had loads of blood tests to check iron and b12 levels, had folic acid for iron levels and they have returned to normal, however I still feel exhausted all the time, even after a good nights sleep I’m still really tired. I occasionally get headaches too which I put down to dealing with 2 small children but I’ve read something about chronic fatigue syndrome that these can be symptoms of. Could this possibly be what I’m dealing with? Has anyone else had experiences with this and the doctors put it down to stress and dealing with children and turned out to be something different? Wanted some opinions/advice before I go to the doctors cause I don’t want to waste their time
