Just cry.
Then you will be able to face it again.
If you don't let yourself feel the sadness, loss, fear... it will only be worse for your nervous system.
Fully feel the emotions and name them.... I am scared, I am so so sad, this is so hard, Im so ****** off, this isn't fair.... etc.
Feel it really deeply and then let it go.
Then- do the best you can to get back up in the saddle and try to be hopeful.
Don't think about next week. Just today and maybe tomorrow.
Be outside as much as you can. Eat healthy foods.
Love Love Love... because thats all it comes down to anyway. Count your blessings, but it's okay to be tragic in between.
