I believe I am addicted to youtube
Why do you think you're addicted to youtube?
There's always some kind of psycho video which makes me wanna watch more videos.
You need to spend your time doing more constructive and useful things. It is wasteful to spend your day watching useless videos on youtube.
Calm down it's not a waste of time, life is not always productive
I understand you cannot be productive all the time and you need some time for entertainment too but it's dangerous to get fixated with something and keep doing it over and over. There are features in phone and the youtube app to track your time, you should closely monitor it and try to cut down the usage.
