Translation Needed

I found a recent note in my late grandfather’s home. Can anyone translate it (Italian to English)?

Does anyone have an idea?

You should have improved your title to make it easier opening your thread, like: “Italian-English Translation Needed”.

I’ve just opened it by chance.

It’s not easy to read at all. It’s written very badly.

It should be:
“Addio a tutti
chiedo perdono”
(the last one is a name surname? Mildolo or something)

Farewell everyone
I ask for forgiveness.
