How to not be worthless?

No.8754272 ViewReplyOriginalReport
Hey, to sum up the backstory, I used to do really well in school but lately I've lost motivation to do well. My grades have suffered immensely, and I waste away almost every day in my room watching anime or browsing the internet. I feel completely worthless, however recently I have discovered a huge interest in pharmacology and general chem/bio. How do I cultivate this into something actually meaningful? What steps can I take to develop my interests into something that can last my lifetime? Any help would be appreciated :)
