I periodically take breaks from social media and delete the apps off of my phone every other 3 months. It's not healthy to be indulging in "fakeness" and it definitely lowers your mental health. During my breaks, i like to indulge in other hobbies that I know bring me joy (like gardening, cross-stiching, and painting). the first couple times i did have FOMO. to deal with this i called up my true friends, actually had meaningful convos with them! Social media has its pros and cons, but if you aren't careful and realize its harmful effects, it can be such a cruel technology.
Grammarly has helped me out a lot. Even though it fixes your mistakes, you can see what you did wrong and learn from it. I also read a lot. active reading can help you so much!
