Kind of bullshit happens to me all the time. It's just a complete headfuck for everyone. I don't think there is a sane way to deal with such disappointments. Sorry to hear this. Write some music about it? That always helps me relieve that horrible angst.
Cheers dude - I'm feeling a bit better now. Just felt like a big smack in the face with a disappointment stick! Tonight was meant to be a release - from a fucking stressful week - but it didn't happen. I'm sweet, there will be other nights...maybe...unless the situation gets too hard. Meh, we'll see...
So why did you live with disappointment for years?
