英语修改!看看以下英语语句是否正确!
Lost all world,for me is not important.Only you are in my heart!
Because you are my all.If you left me,I will did know ,where was I should gone.
(大概意思是：失去整个世界对我来说都不重要.在我的心里只有你!因为你是我的全部.如果你离开了我,我不知道我应该去哪里!）
帮忙修改下英文语句中的错误,谢谢!

答案

I don't care about losing the whole world as long as you are right here in my heart.Because you are all I've got and I don't know where my destination is without you by my side.
