I'm very lucky to still have my mom. She's the only person I'm really close to.
It's so hard for us to connect with anyone, that when we do, and lose that person, the grief is that much more intense. Plus we tend to struggle with change in general, more than the average person.
I'm so sorry you're dealing with that level of grief and sorrow. I hope that you can at least find moments when her words of wisdom ring true for you, and you can find happier distractions that get you through your day!
