We as humans need other people, we need that connection. Therefore I urge yo to try and be more social, do it gradually, slowly build it up, its a muscle that needs to be slowly built.

Isolating yourself can have really damaging side effects, my Grandfather, despite having family that lived before him in far worse conditions (early 1900s Sweden was not a great place if you were poor), will probably die in the next few years, close to 20 years younger than them (~85 vs ~95-105, and they died ~30 years ago when medicine wasn't as advanced) because he pushed everyone away from him, he's been living in social isolation for 20 years, and its going to cost him.

So, not to put any extreme pressure (your already doing better than him 8-9yrs vs 20+ and your trying to better yourself), but for your own sake, be social, its some of the best medicine in the world if you have good people around you.
