Can someone please help me

I have a boyfriend of two months that I love. I know I love home I’m sure of it but lately I’ve been having a crisis (I’m a junior in high school)

The other Friday I was in Math Class and I was making a lot of noise with my pencils when so kid looked over at me and said “keep going” (in a joking way). For the rest of day I thought nothing of it and nothing of the kid. Then on Sunday I kept thinking about that moment.

I asked myself: “why am I thinking of this so much” to which my brain said “it’s because you have a crush on him.”

I’ve been panicking about this for the past week and a half. My mind went off on a wild tangent. I keep thinking I’m gonna have to break up with my boyfriend even though I don’t want to. I feel like I’m gonna cheat (even though I know I’m not because I legit don’t know this kid and I don’t have a chance (if I wanted a chance))

It sounds so fucking stupid and I first thought that I was just having intrusive thoughts because I kept thinking about him. I would be eating pizza and remember the crush thought and then I would think “I would if he likes pizza” thoughts like that. It made me feel immensely guilty to have those thoughts when I’m with my boyfriend. I think constantly about him seeing me with my boyfriend but not to make him jealous or anything It was just a thing I had and now I can’t get rid of it. sometimes I forget about it. I think “hey I haven’t thought of this in a while and then in back to thinking about it.”

I thought I was getter over it the other day and everyday I think that but every time I go back to the same math class I’m back to square one. I want to look at him so fucking much. But it’s not in a crush way. I’ve literally never given this kid a thought even though I see him a lot But I’m so fucking hyper aware of everything he does now and where his is and I’m afraid it’s gonna result me having a crush on him if I don’t already do.

I don’t want to have a crush. I love my boyfriend I’ve considered dropping the class because it gives me so much anxiety I just sit there and panic til it’s over. I honestly don’t even view the kid as human anymore he’s just something that I’m afraid of

PLEASE TELL ME ANYTHING IM PANICKING SO MUCH I JUST WANT THINGS TO BE NORMAL AGAIN.

As a side note I would like to add that I’ve had obsessive thoughts like this before. I once thought I was a pedophile and I once thought that I was gay and I couldn’t get those thoughts out of my head for days (both were not true)

And before anyone says “ if you’re literally scared of him then you don’t like him” but my head says “you’re just tricking yourself into believing that because you can’t face the truth”

Please be kind!!
