UPDATE : I'm worthless...

I recently got hired 2 weeks ago as a medical assistant at the clinic I worked as an intern 6 months ago before giving birth wit my daughter. I was excited at first when I got the call but now my anxiety is kicking in everyday. I wear hearing aids and it's so difficult for me to answer phone calls. I also try my best to keep up with everything but I stress out so much that I forget what I learned. My coworkers seem to be getting annoyed of me. I chose the wrong career 😞. I regret going to school and I have to work to pay off my student loan. I make mistake after mistake and I feel worse each time. I'm keeping my feelings to myself and act like I'm happy in front of my husband and kids to avoid giving them problems. But on the inside I'm falling apart. I just wanted to get this off my chest since I have no one to talk to.

UPDATE:

Thank you guys! It made me feel much better knowing I'm not alone. I'm keeping my head up and staying positive for my kids.
