Anger?

Hello! I have been living with PCOS for 13 years now. Hubby and I have been TTC for 7 and a half years and just recently sought out help from DR. I also have anxiety disorder which I am medicated for (Buspirone 5mg before bed). Long story short, he has me on 10 days of Provera followed by 2.5mg of Letrozole CD 3-7. This is our first cycle using Letrozole (did a few rounds of Provera only, to clean out system) and am currently on CD 13. I am used to rollercoaster emotions however the last few days have been insane. My anxiety goes from 0 to 100 back to 0 in no time. I'm also experiencing a lot of anger and am taking everything personal. I know it's not really me, probably the hormones, but I would love any advice. I am seriously struggling at work and can only imagine what pregnancy will do to me. I'm afraid of saying something wrong out of anger and losing my job! please help
