This is quite blatantly an advert but if you do not wish to contact your company, you can contact “Stiftung-mayday.de” which is a confidential organisation using pilots and cabin crew to help council people. They offer CISM Counselling - Critical Incident Stress Management. Go to their website and have a look through their FAQs. It is something supported by my company (500+pilots) and is openly talked about during each Ground Recurrent.
