Is There Something Wrong with Me?

Lately I have been feeling really tired and sleepy, and hungry all the time especially for sweet things! I am not fat but I keep eating and eating. I get irritable easily and stressed out and emotional and I try to get more sleep but it just gets harder and harder to wake up. Every time I lay my head down for a couple minutes I get this really weird, kind of nice feeling and get so disconnected to reality that I forget everything about my human life, and I hallucinate then fall asleep instantly. It kind of feels like someone increased the gravity and everything's all slow and weird.
Also, I am fourteen and have never smoked or done drugs.

Can you help me please?

Suggestion:

LOL the people who think you are pregnant are ******* retarded.
…unless you're a girl and you've been having unprotected sex (which would be bad since you're only fourteen)

You're probably going through a hormone shift (very common for teenagers) that is causing your body to need more sleep since you are still growing
