It's just I don't see the reason for this photo, not that there isn't one. Like you said, you have a personal reason, but you don't wish to share it. But then why post the picture? The point of taking a photo is to convey a feeling, at least in my opinion, and if you don't want people to know that feeling then what is your purpose?
As for the photo itself, if you're wanting critique.. you got the image in focus which is nice. I would probably crop the bottom so those brighter parts aren't showing, clone the speech bubble so it's all the same lighting, and then maybe give the light in the top left a little more space.
