I personally feel that’s 15 hours well spent at this point in your life.
You need rest and you need the support of others and I’m glad that you have both.
In time things will get better.
Forgive the hockiness of this observation but the word hope and the word home have always reminded me of each other.
On my bus back from work these days (45mins or so) I’m hurtling through winding bumpy twisty roads with very little in the way of street lights. The driver tends to have his or her foot down too so it can get a bit hair raising.
I am in the dark at the mercy of forces I very little control over and yet there is the anticipation of home at the end of the journey. A place of safety.
You too are on a strange journey. You have limited control, you can’t see much of the road and your consciousness is being bombarded with input that can be alarming.
Never lose track of the anticipation of your destination. Hope is there. You will arrive safe and well. If you can’t enjoy the ride endure it. It will be alright soon.
