Hey, man, first off my heart goes out to you. My mom passed away on January 14. Unlike your situation, my mom's passing was totally unexpected. One day she was fine the next I'm standing in a hospital feeling like I took a brick between the eyes. The fact of the matter is that's mom. There is never going to be anyone else that can fill that void. There are no words to tell you everything's going to get better. Life just slowly returns to it's normal pace. You WILL hit moments when something you see, taste, smell, hear, or feel will bring back memories and you'll be overcome. Don't hold it back. Give yourself the time to grieve and let your pain take it's natural course. Grief is very different for each person. There's no right or wrong way to do it, but you need to let it happen. Like I said, I'm still working through my mom's passing, so I know where you're coming from. If you need to vent, shoot me an email or pm. May your family find peace in God's grace. Love to you and your family.
