That line makes me wonder if it's depression, albeit maybe a mild one (so that it's not obvious that that's the problem). For me, the first sign of a depressive episode coming on is losing interest in things, and that reduces that intense concentration that keeps me going for 18 hours on a project without a break.
Anyway, just my 2 cents, there. I agree with those who said to see a doctor, because it could also be your thyroid or who-knows-what.
Pretty much this. There are many things which could cause you fatigue and loss of concentration many of which are pretty benign but some of which could be pretty nasty if left untreated. The losing interest in stuff accompanied by being fatigued and feeling a decreased ability to concentrate is absolutely consistent with depression - these are
some of the
classic symptoms of depression. If I had to guess what was causing it then I would go for some kind of depressive illness. However, like everyone else said, you should go see the doctor imo; none of us are qualified to give medical advice (and certainly not in a forum). If these experiences turn out to have a pathological cause then it could well be something which is easily treatable so you could have a significant increase in your quality of life in a fairly short time. On the other hand it could be something more menacing
SO either way it's well worth the visit to your GP.
