Some of us get to go to AB, but some of us, even though we live a half hour away, don't get to. That's life, bro.
What I'd suggest is perfecting your cosplay, attending meetups and shoots, learning a new cosplay-related skill (or non-cosplay-related, whatever you want), gabbering with everyone here, drawing stuff, and indulge your nerdiness in other ways.
Alternatively, start working out or get a new hobby to fill in your time. If you're busy, you don't have time to be depressed over things like not having a convention to attend.
