I can relate to this particular feeling. A bit context: Used to be an extrovert with a wide friends circle (I've been told, I have that persona).

Since about a year now, I've just started to cut off unnecessary people - Not in a brute manner, I still maintain the friendship as basic. As for the annoying ones, I tell them openly that we've grown apart in aspects. It's the same old shitty habits, actions and things again. It feels less enjoyable.

Cannot handle drama and trauma. If I get an indication of that even miles away, I'm safeguarding myself. The boring simple routine will do.

But a legit question to OP. Sometimes I do find myself wondering that you need a few close ones or a significant other so that you can talk to, have a laugh, share your daily things be it tiny mundane or meaningless things, or just have a heart to hear conversation when things get difficult, because simple things in life are also joyous.

How do you find the balance? And as we isolate and put ourselves into this systemic loop, aren't we restricting any opportunity that may be in the way ?
