I hope I'm not getting annoying with all my "questions" posts, but I need a lot of help!

hehe
So I've tried counting calories before, and it definately did work for me, my only issue is how do you count calories when you go out? Or when you eat something at home, like say a peice of fruit or something. Is there a website you can use to count them? Or do you know of a way to figure it out?
Thank you for all your help and support!!!
