Yes, losing a friendship can be pretty traumatic especially when it was a very close one.

Losing a friendship a long time ago sparked years of insecurity and turned me into an introvert. I would only now just say I was recovering from that. I think people hugely underestimate the damage caused by broken friendships. I hope that you recover soon.

Your perception of things might have changed but your personality is your personality. Your behaviors may change but you are who you are. In time you'll most likely go back to your original state

Yes it can change something within us especially if the friend we lose meant something huge to us.

Yeah sometimes it takes time to understand things.. Sigh
