I also noticed along my journey that lonelieness has to do much with one thinking of themselves too much. After some muh|shrooms madness, that part of the brain that thinks of "I" just shuts off and one is them able to reflect and become aware of their actions, behaviors etc. meditation does this too. It doesn't remove loneliness, but it helps you figure out what it is that causes it. Then you just have to change some actions, get new habits and thus soon or later, loneliness is managed. Same goes with depression, anxiety, stress, anger etc.

However I'm not saying one should go and try mushrooms, but let muhshrooms try you.
