Grief changed my personality

Losing my mom two years ago completely changed my personality and I'm incompatible with most of my friends in the friend group now and it hurts I wish I was the same person. I talk different, I act different I didn't choose to become different but I can clearly tell my friends do not like me anymore.

I've been told that I am much more talkative and majority of my conversations with my friends which were so natural and easy before have devolved into one sided unenthusiastic dry responses. I just wish my entire personality didn't change for the worse I fear it may make me lose my friends.
