Here's
Chimp's Guide to Convincing Yourself What is Not Real Really Is:
1.) Burn yourself out doing school work in one second-year university semester.
2.) Catch pneumonia from weakness due to lack of sleep from doing assignments obsessively.
3.) Listen to your father bitch about work. Constantly.
4.) Act clingy with your very, very, very, very special/close female friend who is on the verge of possibly becoming the other person in a serious relationship.
5.) Flip out and become depressed.
Once you pass this stage, I guarantee that you will be trying to grab a hold of whatever you can to keep you happy, even if that means having conversations with people you care about in your head.
And believing that those conversations actually took place... for a little while at least.
EDIT: I forgot... if you still aren't there after Step 5, write an 11 PAGE LETTER to said female friend. I call that Step Deep Six.
