Disheartened ~= "soulcrushing" Discouraged ~= I am running a race against my peers and I don't seem to be able to keep up. After a month of training; they seem to be getting faster and I seem to not be keeping up at the same grade. "All this effort for nothing" Disappointed ~= I was expecting chocolate spread on my sandwich but it was only jam. (slightly in the direction of "something I expected but did not quite estimate right")
