I'm so sorry. Grief so close together makes an already heartbreaking situation feel even heavier.
My grandad passed in June and less than 2 months later, my mama died too.
I try to take comfort in the fact that they are together but it still feels incredibly heavy. I'm sending you so much love. Cry it out. Hit something. Throw some weight around. Eat all the bad food. Do whatever you need to do to make it through the storm.
And be kind to yourself. Don't feel guilty if you laugh. Don't judge yourself if you dont feel you are grieving the "right way"
Do what you need to do when you need to do it.
I'm here if you need to vent
