Hang in there and if a counselor will help, then by all means give it a try. I think you might consider your Dad may be more resilient than you think. I know you want to protect him from pain. When we love someone, we don't want them to be in pain or suffer sad times. We are humans and can love or feel pain, we cannot escape that fact.

You never know in the end, if it all turns out differently, he may actually end up a happier person.

We all grieve when things are lost or change - it's an adjustment period. Like animals which shed an old exoskeleton, we can also shed the past and move forward to stronger and happier experiences.

I hope you can take care of your own needs because I truly think your parents are strong enough to find their own path through these rough waters. As a parent myself of adult children, parents want their children to be happy and successful. You can reward your parents and put them at ease if you continue on a path of your own progress. If you are down and worried, they will in turn worry about you. That's not a good cycle to be in. If one can find positive in negative and improve things, then all may be inspired. I still think some therapeutic interventions might help. My best to you.
