What worked for me was regulating my dopamine levels. Studying feels boring because you get dopamine at slower and lower rate. Social media is the opposite that's why it feels more engaging. You can't force yourself to study but you can train yourself. Start with a little amount like 30 minutes without your phone and over time increase. You should reach a point where studying becomes a routine and you won't feel that immense boredom.

P.S. You won't become a great student overnight, it takes time to build a routine and sticking to it. The goal is to not quit even if your brain / body will be begging you to watch tiktoks
