Should I call my boss tonight to apologise for lashing out at her today?

I lashed out at my boss today because I was being mistreated and disrespected at work and she told me to deal with it >_o I know I shouldn’t have lashed out, but I got so upset at her response and lack of concern that I just got in my car and drove away. I’m not fired or anything, because god knows they need me and they’re a wreck without me, but I feel like I should apologize to her and explain to her the situation more clearly, because she didn’t understand when I told her. I am just not sure if I should call her now, or send an email… I wanted to call her to meet with her or to explain myself… not sure what i should do, but I want to get it done right away. It is a little late (8:30) so I am not sure if I should call her now or tomorrow morning…. Should I tell her that I would like to speak with her in person or just talk it over the phone?
