should i add my friend back or should i wait for her to come back by herself?

[Hannah]

so i have this friend that i love so much, and that i care so much about. she knows that, and i've always been really sensitive with her, like if i'm attached or something so if she gets mad at me, i get sad. so yesterday she was deleting a few contacts from her phone and i told her in a joke way: i dare you to delete me. and she did. i told her to add me back but she didn't do it yet and i don't have the guts to add her back either. and yesterday at night, i asked a friend of mine to tell her to add me back and that i miss her and that i'm bored and i need someone to talk to, and she took it in the wrong way and she said no. today she told me that i only talk to her when i'm bored and she doesn't like that, i didn't even mean it like that and its not true because we talk like everyday and i love her to death, its like i always try to show her how much i care about her and i don't understand why she took it like that and now i don't know what to do. should i direct message her on twitter and tell her that i miss her and for her to add me back? she ignored me the whole day at school today.. and i'm pretty down because of that, i don't want her to be mad at me. what can i do? help please!
