Is there something wrong w/ me?

I havent really eaten a good meal in a few days. i cant sleep well at night, which makes me more tired and extremely exhausted. i slept on and off today cause i couldnt sleep last night. i have actually gained about 2, 3 maybe 4 pounds. i dont really know if theres somethin wrong or whats going on.
Update: Also, i have been wanting tons of sweets!
