Diet concerns?

I drink 3L of Iced Coffee Milk a day which is 2552 calories. And sometimes (rarely; I just find it hard to do both and plus the milk has more calories then the food) I'll have other food too.. How bad is this diet?

I'm not trying to lose weight and I should't because I'm having enough calories.. cause I'm like really small :( supposedly I only need 2000 to maintain my weight..
Butchyess.. again; how bad is this diet?
Even if you are not gaining or trying to gain weight, you are slowly killing yourself. Tone down on the coffee...a cup a day is okay, but 3Liters! You sound like you have a Death wish. This is nothing short of drinking poison. You may be petite, but, believe me, people who are petite are also prone to Heart attacks and Atrial Fibrillation, which is what too much caffeine in your system can do. Not good...step off of it. Nuff said.
