The first statement is saying that you are in a certain "state." This means that you are in a particular condition. And in this sentence that condition is a sleep deprived meaning "withholding sleep."
The second word is a word used for people who cannot easily fall asleep. It is a true medical condition. However some people use it for when they have not had enough sleep. The adjective of this word would be "insomniac."
In order to explain that you haven't been sleeping much lately, there are many things you can say. You could simply state you are "not getting enough sleep" or that you have a "lack of sleep". If you are struggling severely with getting a healthy amount of sleep, the medical term to use would be "insomnia". You can use any of these sentences or words to describe this situation.
The word 'insomnia' refers to not getting much sleep, especially as a recurring problem. An 'insomniac' is a person who regularly is unable to sleep well.
For example, "I've had insomnia lately because I'm stressed about my job" or "I've become an insomniac because I am too stressed to sleep these days."
We also use the word 'well' to refer to how good or bad someone has been sleeping. For example: "Have you been sleeping well these days?"
Also, 'lack of sleep' refers to not getting much sleep.
