If I ask for help with something and I don't understand, and the more and more confused I get, the more overloaded I am and I unintentionally raise my voice. I'm not getting insulting or berating the person, I'm just, put simply, having a meltdown.

My partner hates this and tells me to learn how to stop yelling when I'm frustrated. I don't know how to do this and frankly I just want to stop asking for help. How do I handle this?
