Make two lists. One, an activities list. Every time you hear something fun to do, put it on the list. Eventually, after a couple years, you'll have nearly everything. If it's on the cheap side it's a good sign, although expensive things can be fun too.

The second list, is a content consumption list. Basically, building a twitter, but without the timeline. Write down categories you like, and people you like, and get a YouTube subscription so you don't have to have adds. After around 2 years, you should be rarely adding people & content to the list.

My advice: have a separate categories for movies to watch & tv shows to watch & only do so with friends & loved ones. Never watch tv or movies by yourself, would be my advice.

I understand loneliness. It can be a sad journey.
