I never had a real, good, long lasting friendship  before with someone who understood me. I have a bad relationship with my parents, no siblings, other friends are very troubled. I'm depressed and very negative.

In school, about a year ago, I met my best friend.
She understands me, cares about me, we have a great relationship.  She makes me feel better about myself and life.

The thing is, I think I'm obsessed with her.
I think about her all the time, wherever I go I wish she was there, she's the center of my life.  I want to tell her every single thing that happens, to share everything, I have no words for how important she is to me.
I get sad when I don't see her for even a day, if we don't talk a lot during that time I get desperate and depressed. When she sends me a message I lighten up even if it's after a long day of talking.

I thought it may be that I'm bi and in love with her, but that's just not  that feeling. I don't think of her like that, I don't feel any attraction, I don't think it's that kind of love. 
We both have boyfriends, I'm not jealous at all - I'm actually very happy for her, I like him as a person and a friend. I really like my boyfriend, but she's much more important and makes me way happier. It's not in the same way - I like him and it's different, it's just that she's my priority over everything.

I just don't know what it is and how to deal with that - it's not normal I think,and I don't want it to be a burden anymore, plus it's getting harder to hide it from her and others.

Obsessed with best friend, don't think I'm in love, don't know what's up and how to deal with it.
