Why am I so mean?!

First off, I am a 19 yr old girl with depression. I know that isn't an excuse for being mean or rude but sometimes all the emotions I experience are overwhelming and I just start to combust. I get irritated by the slighted things and questions, and I fear it's not just irritation but almost a rage. I feel angry from the bottom of my spine to the tip of my head and my body starts to physically react. Like an eye-twitching angriness and I HATE blowing up on my bf but some of the stuff he does just makes me wanna peel my skin off!! Please tell me there's someone else who goes through this sometimes as well and what do I do to combat thisss. >;C
