Stress and complete breakdown

Okay so please nothing negative i just cant handle that rn. But i had a serious meltdown earlier for a good 15 minutes where i screamed and cried and was breathing all crazy and that sort of stuff. It was the worst breakdown ive ever had. Im 12w4d today, and before you say its not healthy for the baby i know this. I completely lost control of myself and i already struggle woth depression and anxiety but this was different. My doctor wont get back to me until tomorrow, so i was wondering should i go to the er to make sure the baby is okay or should i wait until she calls me? Also is there a chance i could've miscarried that way and if so wpuld it happen right away??
