Tuesdays And I Aren't Friends Anymore

Today marks 9 weeks since my Mom died. Tuesdays and I aren't friends anymore.
I have only been talking to a few close friends and family. I have a lot of friends especially a few who also lost their Moms. But as much as I want to reach out to them,  it seems like too much effort. I was never one with boundless energy but since my Mom died, my fatigue level is amplified. Social interaction on a superficial level or for long periods of time isn't ideal for me these days. It just seems harder and harder to not become further withdrawn and antisocial. Often I just want to be left alone from 95% of the people I come across. This isn't like me normally.
