DH (a teacher) almost certainly has PTSD from the past 2 years. DD is CEV and I know that this has put even more pressure on him being in an unsafe environment for such a long time. DD also has diagnosed illness-related PTSD so I'm fairly knowledgeable about what it is and the symptoms.
Apart from going to the GP, are there any other support services DH can access? Plus is there any advice as to what he should do? He has a good relationship with his line-manager and is well-supported in school. He's also recovering from getting Covid 8 weeks ago and is still on a part time timetable.
