1. There are two subjects, where I grew up and when I grew up; the verb would therefore need to be the plural are.
2. Yours can refer to place/date of birth, but not to where/when I grew up.
You need to say something like:
My place of birth and manner of upbringing are/were very, very different from yours.
Where I grew up, and how I grew up are/were, very, very different from where and how you grew up.
