Heartbroken due to negativity...need help?

Im feeling really hopeless nowadays...like i dont know how to put it...

soo i'll start from the beginning...

It started ever since my cousin randomly started talking about

my Mr. prince charming...and it was the first time i ever thought

that hey i have a prince...and there are soulmates for everyone...

well, ever since then, i have been thinking about like how he is gonna be

like, if he will truely love me, if this will happen or that...and thats

all that i wonder about...I play stupid mash games or future

predicting games for every hypothetical situation that pops up

in my head about prince charming... My mind is occupied

with these thoughts...its sooo annoying and i dont know how to stop

I know this is a very weird situation...lolz. But i really need something

to stop me from thinking about him and all. I do have a life, i have friends, but i guess

this is the result of me not being able to do anything over the summer...

I dont know, i feel sooo low whenever i think about the negative

hypothetical situations that might happen... Some one once told

me that this situation is called soulmateism... Im normally a very

optimistic person, but right now i feel really pessimistic....What should i do?

I try to keep myself busy...but after a while, i start thinking about him...

I know i sound desperate, lolz, im not tho and I never had a bf before...lol

But all i want to know, is how to get rid of his thoughts since i dont even know him and i get so sad over him...I know its a weird situation...thats why im asking you guys for help...since you guys give good advice :)
