What's an adjective for someone who doesn't feel sorry for themselves? [closed]

It is unclear whether you want a verb or a noun, perhaps the latter.

A stoic is given by the Oxford Dictionary as

NOUN — A person who can endure pain or hardship without showing their feelings or complaining.

With an example

If you are on one end of the bell curve and need minimal drugs to treat your pain, you're a stoic, a good chap.

The Cambridge Dictionary has the slightly different

adjective — determined not to complain or show your feelings, especially when something bad happens to you.

With an example

We knew she must be in pain, despite her stoic attitude.
