*hugs* Getting help is worth it. And you're worth it. And your friends know that, better than you do, and won't mind helping. And if you go to a professional, they get paid to help you, so don't feel like you're imposing ;)

Seriously, though, I know it can be scary to reach out. People aren't always there to catch you, and they can't always help even when they want to. But most of the time, it's easier to deal with something if you don't try to deal with it alone. And the people who care about you know that, too. So just ask them.
