How come movies/video games decrease the motivation to do buddhist practises?

I practised buddhism a lot in holidays given due to Covid-19. I listen to dhamma and meditate each and every day. When my college started, I was not ready for the exam. I got stress. Somehow I found some interesting videos on a video streaming platform and I watched videos such as movies, gaming videos and funny videos. It helped me to forget the problems. At the beggining, I had a **lot of** resistance to watch that kind of useless videos. But at the end, I lost that resistance. Watching a video became nothing. Even after 2 months gone, I still watching videos. I passed days without doing anything related to buddhism. I can't be mindfull as before. What happened to me? How those videos cause me to lost my interest for buddhism? **How I lost that resistance?** Have you any personal experiences like this? How can I get back to that previous state?
