Hey, everything okay?
First, the correct word is "meaning" and not just "mean" ;)
To keep = continue to be, do something constantly, stay, to have or continue having possession of, conserve, remain. Ex: I keep doing this everyday. I keep my phone close.
To get = gain, regain, collect, acquire, make, develop, receive. Ex: Can I get your phone number? I need all food I can get.
Got = past tense/participle of the verb 'to get'. Ex: I got your letter. He got his camera back.
If you want other explanation, you can contact me again :)
I hope I would be able to help you
