Can i die of insomnia?

No: You can't really die of insomnia as long as you get some sleep. There are reports of someone dying from playing too much video games but probably more from being sedentary than from lack of sleep.

Insomnia: To my knowledge, there are no known deaths directly attributed to insomnia; however, there is a disease associate with insomnia that can result in death. Either way, the effects of insomnia can be devastated and you should be evaluated if you are experiencing it.

Not from insomnia: You can't die from insomnia, but you can die if you go many many days without sleep. When i say that i mean not even 30 mins of sleep. The body needs sleep to recover.
