“I noticed my mom was upset, so I tried to cheer her up” can also mean "i have to cheer mom up because dad was mean to her".
"My siblings are upset, i have to cheer them up" - this is parentification.
I am still very empathic, sensing emotions and reading subtle cues really good - but my brain interprets a lot of stuff as threatening, because all of this sensing was mixed with unpredictability. If you always get the same response, you can learn to work with that - if the response is not predictable, you get fucked up like me.
