First of all, take an English class.
Second of all, don't get her a kitten. She may not want another kitten/cat because her old one was "much better" and another cat could never live up to his/her legacy. Instead, be there for your friend as much as you possibly can- your friend is grieving for the loss of a friend, so it's understandable that she is a little stand-offish.
Thirdly, stop pushing yourself on her. You claim you're not a stalker, but you leave her messages all the time. If she doesn't respond to your calls, it should mean something to you. Move on.
