There is a passage for each day of the year (less than 2 pages of reading) and a theme for each month.
If you haven’t taken a look yet, get a book, or two, on stoicism. Stoicism is the philosophy built on fully feeling emotion understanding you cannot control it, but also understanding you do control your perspective and actions based on it.
This is the original Greek definition anyway. The modern definition is along the lines of purging or ignoring emotion which is detrimental as you said. I encourage you to exercise the classical interpretation and stay far away from the modern one. Your post indicates to me you’re already on your way. Awesome!
PS. You’re right on the money with the drug analogy. Any black market works this way.
Argg, my mom was the same, but she was always working, so I have my space! It would get better when you move out. But for now just agree with them, and in secret do whatever you want, confrontation with the beliefs is not the way to go. And try to avoid being home, go to a friend house to study, or a library, join a club, some course of something you like, even hiking in nature or a city would help to have a little freedom.
Also try to build boundaries with them, don’t let them affect you emotional. I recommend you this book Daily Stoic , hope it helps.
