Can't sleep

You know that person that says goodnight then almost instantly goes to sleep?
Every time I lay down now, as of late, I roll over and my mind just starts spinning with thoughts.
It doesn't stop, and it goes from one extreme to the next.
The high speed chase of thoughts are full of shit that matters, and shit that REALLY don't matter.
They tumble through my mind, making me experience various different emotions.
Some things make me really sad that should really not make me sad.
I would like to lay these things out for you, but I think that's what the therapy I don't have is for.
It sucks.
This morning, in particular, was difficult for me because my heart felt like a soccer ball about to pop after being filled with too much air.
I woke up worried, and stayed worried for at least an hour.
I'm "dieting" after I treated myself to doughnuts, cheetos and pizza last week.
Food: like sandwiches and pizza orrrr... really anything with carbs make me forget the worry.
They knock me out.
I miss them.
