What do i do right now?

Im 13 and im turning 14 in august. A couple of month ago, i told the girl i like that i liked her. I texted her and told her. she texted with only a couple of words. she didnt say anything mean. she was just like ok and oh... Then i texted her a couple of days later that i dont like her... Today was the last day of school. it weird tho cause we look at eachother for like a split second. We got our yearbooks and got them signed. I wanted to get it signed by her and she was walking around. i dont know if she was walking around to get near me. as soon as school started, she walked into my homeroom. we were looking a couple of times. im pretty sure that she wanted me to sign her book. i wanted to sign hers but i was a . as soon as school ended, she went up to me and asked me to sign it. i wrote "have a great summer theresa" and to be funny a drew a messed up heart over my name. on my book, she wrote the same thing "have a great summer. ur asian friend, theresa" with a heart. i looked at other peoples yearbooks and she didnt put any heart next to anything else. i havent texted her or really talk to her in such a long time. the last time i texted her was when i told her i didnt like her. apparently, shes going to a catholic highschool to... i feel like i wasted all my chances.............. i want to die right now...i can not talk to her at all in real life. i can to other girls but definatly not her... what do i do? if i should text her, wat should i text? She might be with her friend cause its the last day and if a text her she would show her friend...i no from experience becaue last time i told her i liked her, she told her friend...shes not the kind that would talk much or text...i really like her but i want to somehow talk to her. it would be kind of awkward to just text her all of a sudden. also, shes really popular and im not that popular.i asked her who she liked last time and she said no one...im pretty much a klutz...should i text her?wat if shes like " how does he have my number". or is he for real? shes adopted and im asian.... her friends will think i only like asians maybe.... this is so confusing... if i do she'll be like wtf. or should i text later when she might be alone.... this is all screwed up. should i text her "is it true your going to a catholic highschool" because i really dont know...help please..PS i want to be friends with her and talk to her and tell my feelings and stuff...if people find out , im fuked...
