Depressive State: Just graduated from highschool.. need advice!!!?

moving to a new place and completely starting over is probably the most fun thing ever!! i lived in the same place my entire life and I started to get shy and depressed there but then i moved out of state and was optimistic and energetic and happy again and made a ton of awesome new friends!! it's so much easier to know who you are when you don't have old friends to influence you because people change all the time and you might not even have anything in common with them anymore. plus, when you move, you don't have to worry about old friends you can just focus of finding friends that fit you like and have things in common with. But with you it'd be nice because you have your brother and he'd be able to introduce you to some people to get you started. I'd go for it!! :)
