Sympathies from a guy who went through the same some years ago!
I could not eat or sleep for a few days, called the Fleet Manager, asked for emergency leave only to be told "sorry not enough captains"!!! So I asked if I could swop my 7 days leave the next month for 5 days emergency now. A few hours later, they took my 7 days and gave me 3 in return!!!!! Honest to the prophet.
A few months later I went to clinic, told the doc I've had enough and to her credit she just asked "how many weeks do you want?"
My flying really suffered for about 6 months so do yourself a favour, go to the clinic, pour your heart out and take 2 weeks off!!!
