Simply put: the lack of work/life balance due to not setting environmental boundaries at the onset of self employment had destroyed your productivity within both work and life.
I suggest continuing to work from an office of some sort - be it the coffee shop, a co-working space, or renting a room or desk in someone else's office, so you can continue to separate your work and life environments.
You can turn on the internet at your apartment, but place priority in what you actually want to do outside of work by granting those things greater space in that environment. If you like to read, have books easily accessible for you to pick up and read. Get a nice chair/couch for you to sit and enjoy reading. Build a nice wall of bookshelves for your books. Join book clubs, arrange lunch/dinner with people who also like to read, etc.
