13 year old bi/lesbian?

[089]

Okay.. This might be a bit long but please read and help me?

I liked girls for the longest time ever! At 9 I wrote it in my diary that I liked them and my mom read it and yelled at me and beat me fore it.. After that I kept quiet and kept things too myself.
She said it was wrong for me too like girls because I am a girl too but... I like them... I like boys to just not as much..
I met a girl on instagram she's 14 and now we're in a long distance relationship (For 5 months!) And my mom don't know about it.. Nobody in my family does..
I feel awkward because My younger sister makes jokes about me being bisexual or a lesbian I just sorta laugh at it or pretend I didn't hear her.. I want my family too accept me... I feel a bit left out and it SUCKS!

I like boys their attractive I'm not attractive to them sexually though.. Never have been.. Only girls..

I'm scared and I don't know what too do! My mom said that when I was younger I always liked hanging out with girl more then boys.. I hated boys A LOT

All I'm asking is:

Am I a lesbian?

How do I get my family too accept me?

I'm scared and I don't know what too do..

I been thinking about it a lot lately..
I have nothing against LGBT people


I have a aunt she said she wouldn't care if someone liked the same gender and that if they like the same gender it's okay it made me happy... But I'm still scared too tell anyone that I like girls..


Help me figure out how too tell me family and not be afraid..
