Oh J.T.,
Just the grief alone is overwhelming. Your son can take care of himself. He has already proven that he can. It's summer and he won't be cold. It will be like camping.
It gets to the point when you have to let everything else go and protect yourself. You are at that point. It won't take you long to build your strength again. You need to take care of YOU right now.
Let everything else go until you are ok. A couple of months ago, I knew that just one more thing would have sent me to the nut ward. I had to stop everything and protect myself. It took a couple of weeks to regain my strength.
You are the most important person right now.
I love you,
MG
