Professionally, that's exactly what I've been trying to do over these last many decades. It's difficult because sometimes you will lose your sense of hope. Again, I come back to the idea of having a huge responsibility but not having the power to implement the changes. It is absolutely horrible to have to deal with the scenario where your veteran is semi-stable and then Veterans Affairs comes in with a denial or whatever. Then everything blows up again.
The pressure on the caregiver is also part of what causes relationships to end. These people are not superheroes. They are providing services that are equivalent to a superhero's, but they don't have that resilience. Sometimes the circumstances just blow through their resilience.
All I can say is that it's hard, whether you're a professional like me or a caregiver. It's difficult to have to deal with this day in and day out, never knowing from minute to minute if there's going to be a huge blow-up of whatever.
