Leave the nest?? If so, how do I tell my family...?

Okay so i just graduated high school.. The week of graduation was a very stressful time for me because i was trying so hard to pass Pre cal and my legal guardian (my uncle) and i got into a very discouraging argument about what my chances were of graduating.. To make a long story short, i was called a disappointment and all those wonderful things that parents say but sure enough i graduated... After that, i came back to my hometown to find a job to save money for college and i will be here for the next 6 months. I'm pretty positive my uncle is expecting me to move back with him when the six months are over. But I look back on my years of high school... And he really didn't offer much help besides financial help as well as a roof over my head.But with my dad in prison and my mom out of the picture, i really needed some support with my interest in my extracurriculars, and just needed somebody to be there for me. When my dad was around he would do anything to help me in anything i was struggling in. But my uncle suggested i find help from somebody else.. Honestly i felt like he didn't care about what i did at school. I spent my whole high school career in choir. Music is my life. And he would make no compromises to see me perform or at least try to be involved... Maybe i just compared him too much to my dad... but i really needed him and he wasn't there... And I'm sure when i go to college, i will have a hard time getting around since he is so focused on HIS life HIS plans HIS problems...whatever! One of my close friends invited me to move in with them... And honestly i really want to. But I have never been away from my family... I'm not sure how my relationship with my family will change if i do move out. And i dont want to shut them out of my life or anything... but i feel like i need to move away from them in order to grow... I'm just really scared and confused.. I love my family... What should i say to them...??
