I think a little bit it’s just that people typically like labels. They want to fit neatly into their little labeled box and the more labels they have, the more unique and/or complete they feel.
I really rejected labels as a teen, I hated the idea of it. Now I realize they can be useful for some things, and you know, if my trans brother feels better because his label is now male, that’s fine it doesn’t hurt me any to call him what makes him feel good.
What exactly is an “emotional outburst” for you?
There are a lot of things this could mean, ranging from more benign (sobbing) to extreme or scary (throwing things or screaming or worse)
If it’s anywhere near the latter then you need to figure out how to manage those symptoms of your mental illness before you’re ready for a relationship.
