mi madre buelbe estar mal
mi madre buelbe estar mal is buelbe from doler???
"buelbe" is probably vuelve as in my mother is getting sick (again).
Hello and welcome to the forum.
"Buelbe" looks like a misspelling of "vuelve," which means "she returns" or "she is again..." In this context I'd say it means "My mother is sick again."
I agree with the previous answers. It is "vuelve," which is from "volver."
The sentence, if I may add, should be "Mi madre vuelve a estar mal.
