Is it normal for me to obsess about and stalk women when i'm one?

there's this teacher at my school who im infstuated with. i WANT her. see, im a chick too, but i already know imma les. the problem is i get so horny whenever i see this teacher. i dunno if she knows that or not, but i don't care. i want her to want me, but im kinda fat and she has a perfect body. she's gorgeous. no. scratch that. she's SEXY. today i saw her in the hallway and i said her name. she looked at me and, (i couldn't stop myself,) i moaned. i've never had this problem before. i've never wanted anyone so much in my life! i have this theory, see, that if i seduce her into fucking me, (that's tribbing,) then she'll make everything right. i've liked her since the first day i met her. i dunno. something just clicked inside me. i think she's my Soulmate. but she doesn't want me. how am i supposed to get her to want me, kiss me, and fuck me, and not stalk her and obsess about her? please tell me. i'm having major issues with her.
