Could stress be the reason my face is broken out?!

My skin for a good few weeks has been spotless. I have never had a problem with acne, just a few breakouts here and there or a zit a couple places. But my skin has been so clear recently. I've been taking really good care of it, it's felt healthy and smooth..everything was great. I also have perioral dermatitis (for those who don't know what this is, it's an eczema-like, itchy, red rash that spreads like wildfire and is found under the nose, around the mouth, and on the chin. It's very sensitive and extremely, extremely hard to get rid of. at least for me.) and even that was cleared up for the most part. Then a "verbal altercation" made me so mad it felt like my blood was boiling, I was yelling and angry for a few days straight, and very very very stressed out. Literally by the end of the day I had already gotten 5-10 blemishes, my perioral dermatitis came back FULL force, really really bad and all over below my nose, just as bad as when I first got it.

Could this have been caused by that very stressful event?! Please, please help me. This is so unbearably uncomfortable and embarrassing and I want my skin back clear like it has been. Just the thought of having acne and dermatitis all over my face, being itchy and embarrassed is stressing me out even more. I need some kind of reassurance that it will clear up again.

Here's what I've been doing
1. I use Principal Secret face wash morning and night. It's very gentle and good for my skin type. I follow up with the lotion that comes with it.
2. Polysporin was what originally cleared up my perioral dermatitis bc the crap the dermatologist gave me didn't do diddly squat, so I put a light coat of that on at night
3. I use all mineral makeup when I do wear makeup, which only happens 1-3 times per week anyway
4. I just thoroughly cleaned my makeup brushes
5. I changed my pillow case
6. My hair is always out of my face

What else can I do???? Pleaseeee helppp meeee
