I don't know what to do.

Recently I have some really bad situations with my relationships and friendships, I really cannot figure out if people are acting to be good with me or I'm just not good enough. I really just want a loyal friend maybe just for ONE DAY PLEASE. My main bsf let's call her Olivia (not actually her name) . Me and Olivia live in different (more than streets idk) but we still do go in the same school. We both know the problems into our lifes and we do vent them out to each other but when it comes to her venting to me I really try to help her and I really dont know what to say but at LEAST I TRY. But when It comes to ME VENTING TO HER she says absolutley NOTHING. She stands there quietly and wonder if I should stop trying to vent to her. I am trying to make this friendship work while she dosen't. How I said, we live very far from eachother and she has a big friendgroup in there and of course she has a crush on a guy there, (thats why she hangs out with them). While I do not have much friends I only have Oilivia , (lets call her Lily) and thats probably all. I feel like Olivia hangs out with them since they have more "drama" and I'm actually just boring to her. And I understand but like, she always ignores me and I never get to hang out with her for example this day we were supposed to go ice skating but she said she was "SICK" and her mom wouldnt let her. I never hear or see her coughing like bitch, who do you think I am? She literally makes me cry and I cannot stand it. I try to take action and say what shes doing wrong but again, she acts mute. We are now on call and we havent said anything to each other for 40 minutes already. Also a bonus, I think I know why she dosent hang out with me. She stays there and ignores me for HOURS while I do nothing and I only go out with Lily for ONE DAY. As I said I only have Olivia and Lily on my side. I lost more than HALF OF MY FRIENDS in ONE MONTH. (also I lost my boyfriend the same month.) Since I'm so boring I have no one to vent to and no one takes me seriously. I seriously need someone to wake her up to reality and hit her on the spine to sit straightly and see what serious damage she has done to me.
