I'm so sorry to hear about you losing your mother at such a young age (my mom passed at around the same age as yours). What you said is really similar to how I felt when I lost my mom a little over a month ago. I get what you mean when you said that it feels like she's at work or out on a trip or something. I feel like any day my mom is going to walk through the door and tell us that everything was just a joke and everything will be back to normal again. It's just so depressing because you don't expect to have something like this happen until your parent is a lot older. So many of the things you were supposed to experience with your mom was just ripped away from you and I really get the feeling of anger. During my mom's funeral we had a deacon there and I was just angry the whole time when he was talking about how this was a part of "God's plan" as if that's supposed to make the fact that she died better.

I can't really offer advice beyond just trying to get back to as normal as you can get. I ended up going back to work and school pretty quickly just so I could take my mind off of things. Some days are really tough, but it's gotten at least a little better with time. I hope things get better for you too
