You certainly aren’t bothering us, that why we are here.

You mentioned the family support and excellent medical care, which is critical. Continue to rely on them and continue to let them know how you are feeling.

What you are feeling is perfectly normal. Before my accident I never spent one night in a hospital; when I had my accident I was in hospital for two months. The experience of recovery has given me new appreciation for family and others that continue to support me. I have developed an enhanced sense of gratitude. You mention you already have those good days, celebrate those. On bad days think of those good days, and that overall you will continue to get better.

There is a book out “What Doesn't Kill Us: The New Psychology of Posttraumatic Growth” by Stephen Joseph PhD that I found helpful.
Best to you in your recovery journey.
