Some days after being dumped you will surprise yourself with your resiliency, and start to feel like things are looking up.  You may spend time with friends, do activities that make you happy, or just have a more positive outlook because of some misfiring in your brain chemistry.  I think of these days as gimmes, and there are only so many that the heart will allow before you start to feel shitty again.

The Mountain Goats' "Get Lonely" talks about the inevitability of loneliness, despite your best efforts to escape its clutches:

I will rise up early and dress myself up nice
and I will leave the house and check the deadlock twice.
and I will find a crowd and blend in for a minute
and I will try to find a little comfort in it.
and I will get lonely and gasp for air.
and send your name up from my lips like a signal flare

Not exactly comforting, but part and parcel of being dumped,

unfortunately.
