Survive it
The thing about healing is that it's not just going to suddenly get better. Some days you'll feel fine and some days you wake up already feeling like shit before you even open your eyes. Some days you'll be able to smile through the pain and some days you'll cry into your pillow wishing for it all to be over.
Healing takes time. It's the dumbest cliche of them all, but it's the only thing you have. Time. You can keep trying, no, you have to keep trying to make it better, to find things that will make you feel better. They're there, I promise. You'll laugh again, you'll love again, you'll love living again. And some days you'll come back home and crash and break and cry again, because that's how it works. That's how the pain works.
You are hurting and that is alright. You have to learn to live with the pain and you have to learn to survive it. And you will survive it.
