solitary, sentenced, alone
I finally faced the fact that it isn't a crime not having friends. Being alone means you have fewer problems.
The best part about being alone is that you really don't have to answer to anybody. You do what you want.

When so many are lonely as seem to be lonely, it would be inexcusably selfish to be lonely alone.
