Is there such thing as an internet addiction?

so just wondering if internet addiction is an actual thing?
currently going online is the first thing i do when i wake up and the last thing i do before bed, it even puts me to sleep, most days i will spend 10-15hrs per day on it, and i'm not kidding.
i never realized i had an issue until my laptop crashed and had to be repaired it after 1 day i because seriously angry and depressed, had to borrow a family members ipad to get online and watch videos it was only then i started to feel better… So is it an actual thing?

i struggle with a drug addiction as well which currently working on staying clean!

Thanks for your help!
