I agree. We all have struggled, and still continue to struggle with self-concept. Always on the outskirts or the edge of.. 3 steps forward, 5 back. Going back.. is just part of the process which now I have accepted for myself. Algorithms are never linear, neither is growing.
Being in a room full of people and feeling extremely alone does happen, to us all. Nothing wrong in it. We all have a path, a journey. Doing what feels right. Be patient with yourself and your peers. Interact and engage when you can, no reason to force anything. Just be. Slowly transition between the conversations.
