This kind of entry doesn't ask for corrections here, but that's what I want to do for you here. O.K.?

I am so sad today! Because My grandmother was sick this morning. She had cerebral infarction and she had been was sent to the hospital immediately. All of us were worried about her so much. Fortunately，everything were was going to be better. My grandmother didn't have too much trouble. When I knew about how she was，I was so happy about that. I hope that my grandmother will live longer and longer. God bless her！

i wish her good luck.

I see often this error, almost always done by Chinese background users:

word word word.Word word word

Correct is:

word word word. Word word word

Each punctuation is followed by a space. Tom did that correctly too.

God bless your grandmother. I remembered my grandmothers :( 

dont worry,everthing will be ok
