Peace of mind

So I work in a retail pharmacy and it’s a very rough side of town , the clientele is awful, I’m 14 weeks pregnant and today we had a patient who just off the wall crazy there was no trying to talk to her or offer solutions anything I offered seemed to just escalate her dramatics , any who during this or deal my heart rate had to be high cause I have wpw which i leads me to an already higher then normal heart rate and it was beating so hard I thought it’d come out of my chest and I could feel the babies moving and I was shaking and just really upset and now I’m worried about my babies because I can’t imagine my heart rate or blood pressure were normal during this time . And I’ve felt little movements but I mean I felt like I had jumping means in my belly and I’m just worried about them .. do you guys think everything is okay ? Am I being ridiculous.. probably am... I just want to do everything I can to make sure I have happy healthy babies and I’m under so much stress at my job because these people are ruthless , and when I took this job no one ever told me what to expect as far as clientele the store I came from was very high end neighbor hoods you rarely had an issue if you did it could be fixed quick , I took this job for higher pay but I don’t feel like money is worth it if it’s going to hurt my babies with the stress I’m under while there ... advice ?
