I just spent quite some time searching for a comic strip I saw years ago on the internet. Didn't find it. I really liked it. Keywords: balloon, heart, love, lock, share, comic, strip. Nothing.
It was about how when you don't share stuff with others and don't take risks, then no one can hurt you, but you are also sad and alone. And when you do share stuff with others you give them the chance to hurt you, but all in all you are much happier.
Strigoi, I know that feeling of having shared too much. I probably still share very little, to very few people whom I trust. But when I look at it a long time later those things which I regretted I shared were never actually used against me. All in all it was a good thing I shared them.
If you share stuff publicly there will always be a risk of someone mocking/disliking/anything you for it. But if you do it here then I'm sure there will also be people who read it who can feel with you, try to understand and help you and who are just generally trying to be nice.
