I was out of line at work today

I just had a bad experience. I customer came back with a complaint and I was so wrong to have the attitude I had. My boss told me u need to work on it. Nondy knows I'm pregnant. And I started crying! I didn't deny anything! And now I'm so messed up! I will accept any consequences. I can wait for my 1st prenatal check up because I know I need help. I plan on asking my doctor for a recommendation on helping me with my hormones. I know I messed up by spazzing on a customer! That should have happened ugh!
