Hi Angel, I also carry my heart on my sleeve. What helped me is to take care of all of my unresolved emotions and then they weren't falling out all over the place. It's like having a ransacked room with everything all topsy-turvy and a mess. Taking care of your unresolved emotions is like picking everything up and putting it in it's place, throwing out what isn't useful anymore and folding/tidying everything else. Once you do all this "housework" the only things that you have hanging out on your sleeve are your current emotions in response to your current environment which is much more manageable. Having a backlog of emotions packs the house and makes things much harder to deal with.

And oh yeah, I was also told by people to not let things bother me. I think that they were wrong. If you are sensitive, you are sensitive. I think that the above way is a better way to deal with it.
