That was my issue. Everybody's is going to be different. Regardless, it's always ultimately a personal problem, with a personal solution, not one with society. Only you can know what your intense longing and pain actually require, and only you can take action to make it part of your life.

Calling it a philosophical problem isn't helpful because philosophical problems don't have solutions, only approaches for thinking about them. You're effectively saying that you don't want to not be lonely.
