Thanks to
@shelley262,
@PenguinMum,
@Viv19 and
@DJC3 for all your kind words. I was a bit down earlier and I must have had a kind of rant back there. All your kindness has made me feel better.
Maybe it was eating the salmon and broccoli as well that helped me feel a bit better. Of course, it helps staying away from mirrors! Have to look into armchair yoga - the nearest pool is 7 miles away, they don't have a class that I could join and anyway, there isn't a swimming costume that would go round me.
My diabetic nurse hasn't been any help at all, nor has my GP. Never mind, though, my better self is beginning to emerge this evening and I can laugh at my foolishness. After all, I don't have to look at myself so, as I told myself when the scar appeared and stayed on my face after surgery, it's not really my problem, it's only a problem for those who have to look at me and if it is a problem for them, who cares?
