Permanent losses will always come in life, I've had too many. So you keep of going because there is no other option. However, we are still alive so there is always hope that the future may yet be brighter than yesterday. At least I hope!
Hopefully the temporary stuff will move on sooner than later. However, I know exactly what you mean and completely understand it.
I've not been in a good place lately and it has lingered for a few days and I've been in a reflective mood and sometimes the struggle just continues and it's difficult to shake yourself out of it.
I do understand what you mean. We're and we have no option other to survive.
