@katz ,Sounds like our normal, to shove and deny feelings. Part of the reason we are here. I still do it. And because we have held on to it so long, and others things have piled in on top of it, we all feel we are going to explode and disappear if things start to surface. We do understand.
You being able to cry when your mom passes is not something for you to end up in the hospital over. That is a very normal, and sometimes over the top reaction to loosing our moms, regardless of our relationship with them.
And as far as grief, we really can't make it happen. It will happen when it does. I know that's not an answer, I just know it can't be forced.
Do some self care things, sometimes as simple as doing deep breathing helps. We tend to breathe very shallow or , I catch myself, holding my breath.. you can excuse yourself, and find a private place and just take some slow deep breaths. let it out slowly.. do this until you feel your self starting to relax, then do a few more.
I'm sorry you are facing the loss of your mom and feeling everyone will be watching you. Maybe they will be caught up in their own feelings. We are here for you if you can take the time to text or go to a computer...let us know what's going on so we can be here for you.
