Why do i hate being alone or away from my friends? Do i have some kind of attachment issue?

Everytime im away from my best friend brianna i get really depressed and i feel lonely and start to' cry. I always hate being alone and i love my family and everything but i try to' get out of the house as much as possible. I always want to' be' anywhere but home most of the time. No i dont live in a violent or abusive household. Everything is fine. Right now in sitting in my house and i called brianna and she said she couldnt talk cause she was busy nd now im sad nd ready to' cry. She always has all these places to' go nd all these things to' do nd all these people around her while Im just sitting here bored by myself staring at the cieling while she has all this commotion going on in her house. Theyre cookin and talkin together(her nd her family) and her moms always yelling. I know it sounds wierd that im saying her mom yelling is a good thing but i just hate the quiet. She yells "do your chores nd clean your room nd dont touch that!". And im alone my moms at work and my dad just Plays Xbox ALL DAY EVERYDAY! So what the hell is wrong with me?!?!?! By the way im 14 if that helps.
