Words of Comfort for Maryann

Maryann, I don't really know you all that much. And I hardly know what's like to lose someone close to you. I guess I could tell you I'm sorry, but I'm not sure how that could help.
I'm not sure you're going to read my message, 'cause there are so many posts from people caring and supporting you.
But just in case you see it:

I believe I cannot understand what you are going through, since I have no experience of that sort. I only know that no one should be alone through this, although, I imagine, as close as we are to you, we can't take away any of the pain, nor comfort you enough.
But if ever need to speak, not only about this, but about whatever, I'm right here.
I'm a stranger, I know. But sometimes talking to a stranger that's miles away from you, is easier, and might help you get closer to yourself.

I'm so frustrated 'cause I can't find the right words to say to you, that I can't help you enough.
But, I guess... there are no right words to say in this situation, are there?
