Learning to deal with life's little disappointments is a big part of healthy mental balance.
To that end, I would suggest volunteering at a hospice or a homeless shelter in order to gain some perspective. If that doesn't work, SSRI's have been known to generate results, as has cognitive-behavioural therapy.
