Do you think I should stop using the computer so much? And quit all my stupid computer games?

I play really retarded games where you're in a virtual world, and you can dance and listen to music. and it's so cool..but i dont tell anyone i play it. theres also this other game that me and some of my friends play once in a while. like a kiddie game. and im on the computer SO much. its kind of embaring because 9 times out of 10, my sister's friends come over and im always on the computer. i dont want to become like..anti-social. the only reason im so worried about it is because my mom makes me feel stupid about it and always gets mad about me always being on the computer. so what do you say? should i just QUIT. even though its so addicting.i want to get like straight As. i realized how stupid this whole computer thing is. if i quit it all, ill probably be miserable and bored. but i want to get used to it and do productive thigns instead. WHAT DO YOU SAY?!?
