Worst nightmare came true- Mom suddenly died - I feel like nothing even happened.

Sorry for posting so much on here but I just don't know what to make of this. Just moved into a new home 2 months ago, feels like yesterday that we were checking the place out, excited to be accepted etc.

Now? Just me and my sister. My mom's room is something I just walk past. That closed door. It's like life has two modes of operating. All or nothing.

If you stub your toe - It hurts
If you burn your arm off - It hurts until there's no nerve endings left.

I am telling you directly. This feels as though my nothing even freaking happened. No that I am cold, heartless, none of that. It's just... a flatline. My body is not allowing me to realize that something is terribly wrong and that I should be freaking out.

Am I heartless or evil for being able to go about my day? The pit in my stomach is there but the reality is being cordoned off.
