Is it impossible to manifest a sp after years of no contact?

Is this impossible?

I don’t get long crushes like this often, the other crushes ive had fades over weeks or month but this one has been years.

Im 23 years old now and Ive liked him since grade/year 8 in high school.

We never really spoke or acknowledged each other. We only spoke once on instagram when everyone was doing the rate me challenges🤣 the other time we spoke was when my classmates was teasing me and told him that i liked him but i denied it and started crying💀

I didn’t know i liked him then but then i started to catch feelings after they teased me.

Times passed and i forgot he existed until i got a random ass dream about him yesterday and now i cant get him off my mind. He probably dgaf about me or even remember who i was but i think im crazy😭😭i don’t think its normal to have a crush for this long which i barely know him and spoke once to him in my life.

But is it impossible to manifest this sp?
