Uhhhh so i just read this comment and imma give you some suggestions I follow when im too deep down the no productivity only bl black hole:
Switch off your phone. Might sound extreme but sometimes when i think i screwed up and wasted away my day reading bl,i even delete my account. That keeps me motivated to do something. Or et the battery drain and hide the charger.
You're in control of yourself so imagine yourself doing well and just do it
Make tiny schedule AND STICK TO IT then eat something nice when u accomolish it
You may tell yourself stuff like this mangakas are successful and fictional characters are well,fiction- i cant stay jammed on unimportant stuff
Or last,
Set a reminder, work for 20 mins- have a30 mins rest and get up when the alarm rings..that way you'll do something
Long but this helps me
I can't stop reading bl mangas so, my module and school activities got piled up =_= I'm so screwed!! I'm so freakin' depressed right now!!! What?! Should I just get a rope and hung my self?!!!!
