I wrote a poem when I was about 12 that expressed that very thought, and for some reason I've remembered it. I'm no poet, as you will see....
There are times in my life
when I can see no end
to a problem that causes despair,
but solace is found in the comforting fact
'twill be another the following year.
I'm not sure if that's pessimistic or optimistic....realistic, I guess.
I actually did punch a hole in the wall once when I was so angry with myself about drinking too much the night before. That really helped (not), as you can imagine.
Hope you have a better day tomorrow, Fantail :-)
