Do I have the right to be angry?

Ok so, it's quite a long story, but I'll try to shorten it a bit, so I started liking this guy, and I tried to impress him, I of course failed. But then my friend started noticing that this one guy started acting different around me, I didn't really notice, then she runs up to me and says she overheard that he likes me, I was surprised and so not expecting to hear this, but I didn't care, I didn't really believe her, because you never know if she heard it wrong. Then she wouls point out when he was acting weird, so I did notice, then I couldn't help but feel a little stalked.. anyways, after winter break we came back and because I started liking him after a while, she decided to get involved, so one day walking home, she screams out really loudly to him "Brit likes you!!" I of course deny it, because I don't need the world to hear it, and I'm still a little scared of getting heartbroken, I try not to be, but I got really badly heartbroken, and she KNOWS about it too, she knows how bad it hurt me. I was a little annoyed, then she started getting worse and worse, whenever he was around she'd be like "look theres your boyfriend" and even though i knew what she meant i acted like i had no idea what was going on. id be like "what? i dont have a boyfriend.." "huh? what are you talking about?" id say when she said tht stuff, she would then later ask why i keep doing tht, i keep saying tht i dont like it, and not to do it, because im still a little scared and i'll deal with it myself, she doesnt need to step in. then, she looks his number up in the phonebook and threatens to call him, she sends him an email saying i want to have with him, and thts WAAAAAAAAY off (I'm only in grade 9!!) at least she TOLD me she sent him an email saying tht, thing is, she sometimes lies to make things more interesting, we know tht shes lying, we just let her keep going, because its fun to make her think we believe her. Thing is, when she lies about what she says and does, or when she lies about what I say or feel, or when she lies about what my crush says or does, thts too far, i mean, its ok to make up an interesting story about something that happened at an amusment park, tht i dont care if she lies about, but when you lie when someone has feelings for another, thts too far, and someone could end up hurt. im afraid i could get hurt again, and im not going to let myself get hurt, i told her today on the phone tht i was angry, and sent her an email letting out my anger, i told her i will never tell her anything important again, because i dont need her ruining anything for me. I thought I should show her how bad it feels, I was going to send her crush an email saying some total lies, like she did to me, she begged me not to, and I said "why shouldn't I? you did that to me." she keeps telling me tht my crush likes me, but I won't believe it unless he tells me himself, she also says tht she's told him like 5 times tht i like him. she says he just smiles, but i dont know if thts true, i dont know if she actually has told him, all i know, is he doesnt act any differently around me, but he doesnt really stalk me anymore:P (he stopped after break anyways, before she even stepped in.) I've told her to but out, but she says no. she wants me and him to be together way more than I do. its a little weird, especially when she keeps saying "go have with him." i mean really - no. im only a 9th grader, and I'm like 14 1/2 years old, thts seriously wrong!! anyways, point is, Do I have the right to be angry when she keeps doing things I tell her not to and she knows that I'm afraid of getting hurt, and she's taking it too far. Is it ok to be angry? Should I get a bit of revenge?
