Sleep

It's now almost 3:00 am where I live and I can't sleep.
I have trouble with sleeping for almost 5 years.
Most night I sleep about 5 or 4 hours but some night I don't sleep at all.
I just keep over-thinking.
And keep thinking about how fat am I and what I'm going to eat tomorrow.
What will I weigh? Should I starve? Or eat an apple? But what if my dad forces me to eat?
Every night the same worries. And every night the same fat.
Life would be so much easier without food.
