Dear Woodman,
My heart goes out to you.
As MorningGlory said, it's unbearable now, but you will be ok. It will take time, though. Grief is hard. Really really hard...but you can get through this....tiny steps, keep breathing, keep reading here.....
May you have the exact support you need when you need it. I believe you will. Keep breathing, keep crying, and then..breathe again. --it comes in waves.
