It's hard isn't it? I know how you feel. Limbo is a pretty tough place to live.
I wish I had some poignant advice I could give you but alas, there is none.
It's one of those things that just takes times, and lots of it. Just know that you will not feel this way forever. This is but a small chapter in your book.
You will smile again, I promise.
Allow yourself to feel how you feel. I truly believe that our hearts can only handle so much pain before it forces us to detach.
Everything that you are experiencing is completely normal. Think of all the heartbreak country songs there are. Those were all written by people that have experienced exactly what you and I are experiencing.
You might not have H right now, but you have all of us. And we all care about you and are rooting you on.
