had a mental breakdown right in front of my doctor and now I have to stay at home for the whole week... I'm so scared that I'm going to lose my new job because I'm already missing in my fifth week ...
You should tell them that you are in fact having medical issues, and have a doctor's note to let them know it's legit. I hope that works; I'm sure they'll understand.
send them a mail now with doctors note ... sadly it doesn't make a difference if they'll understand or not, I'm still on employment probation until February that's why I'm so scared to lose that job...
