I don't know what you looked up but this the translation I came across.......
perfer et obdura; dolor hic tibi proderit olim Be patient and tough; some day this pain will be useful to you.
Sorry but I didn't take it as a negative quote, I read it as learning from something that might help you later in life......maybe I'm wrong.....but there was no wrong intention there
