this is my message in my shout out in my facebook account

I FELT SOOOO UNDERWHELMED THIS AFTERNOON!!! HOW I WISHED I HAD BEEN GIVEN THE TIME TO SPEAK FOR A VERY IMPORTANT MATTER IN CONNECTION TO THE AGENDA... IF IT WAS NOT ONLY BECAUSE OF "YOU" I COULD HAVE BEEN AWAKENING THEIR MINDS.

does my line "I COULD HAVE BEEN AWAKENING THEIR MINDS" correct? please check my words.

What a strange idea! You mean it's common for people to shout at strangers from their Facebook page now?
Don't forget to use capitals where they should go - at the start of a sentence. And remember that a full stop is needed at the end.

"I FELT SO [STRIKE]OOO[/STRIKE] UNDERWHELMED THIS AFTERNOON! [STRIKE]!![/STRIKE] HOW I WISH[STRIKE]ED[/STRIKE] I HAD BEEN GIVEN THE TIME TO SPEAK [STRIKE]FOR[/STRIKE] about A VERY IMPORTANT MATTER IN CONNECTION [STRIKE]TO[/STRIKE] with THE AGENDA. IF IT WAS (were) NOT [STRIKE]ONLY BECAUSE OF[/STRIKE] FOR YOU, I COULD HAVE BEEN AWAKENING THEIR MINDS."
