Mox,
Solid advice above. I am right there with you. Occasionally my mood sours and I start to ask the same questions. Stick around...when you hit 20 you'll wonder what you were thinking.
The grass appears greener but unless you are already in the club, it is brown. If you make the leap, plan on waiting outside in line behind the velvet ropes with thousands of others on the off chance the bouncer lets you in.
Good luck and keep your head up.
