No. It isn't really temporary. It will always be something. I try to proceed with an attitude of gratefulness, even if it is only for peach pie. I lost my mom last year after a protracted illness and I got worn pretty thin. But I loved my mom and that means you gotta take the good with the bad.
I found out that if I kept my mind on being grateful for what I had, even if it was kinda meager sometimes, I felt better and acted better.
It's kinda stupid to say "It could be worse", but it could. Is the glass half empty or half full? If it isn't half full, lie and say it is.
Existence is a very subjective thing. Try to get some exercise and eat right. You get worn down and kinda neglect yourself when you're in one of these things, but try not to.
You might be beat to shit, but you still got a gig to do. People that actually crack up don't ask questions like "How much can a person take?", they just crack up.
People are pretty durable.
