So sorry you are hurting. I'm sure you've done a lot of growing up since you were 17. When we're young we all make mistakes. Maybe they're still angry about you moving out but that's in the past. You can tell them that you apologize for any pain you might have caused them in the past and that you just want to be forgiven. Tell them you need them in your life and love them but you don't deserve all the negativity. Hopefully they will hear what you are saying and hopefully they will be willing to rebuild your relationships. I wish you all the best!
