Is it normal not to know if the gym coach likes you or hates you ?

Is it normal to think that my gym coach doesn't like me that's why she's bitter , mean , sends me negative vibes when i am around her ? . I am a female college student , and the Gym teacher is a female (who there is a rumor that she' either bisexual or a lesbian ) anyways , she always critisize me or make fun of me ,she will menton things about me and i know that she knows that i like these things hiiden . she'll get info about me and spread it to the whole gym class , like for example i'll go to the beach and eat alot , she then comes to the class and says "guys why are you lazy ? , you are not at the beach and this is no restaurant " ,or she'll put songs on what i am thinking or feeling , like at one time i was thinking that she's too good to be true , then she puts the song "you're too good to be true ' and stuff like that . I don't know if the excessive attention towards me is because she likes me or hates me . is it normal not to know if the gym coach likes you or hates you ?
