I'm at a loss for words

My wife’s primary caregiver is me. My Personality Disorder and Diabetes are among the conditions she suffers from. It has been roughly six years since I began providing full-time care for her while also working full-time. There is nothing more I can do with her, and I’m at the end of my rope. As the NHS and my friends and family aren’t interested in helping me, I’m at a loss on what to do next.

This sounds sad and lonely.
I hope that something can resource and lift your spirits somehow.
I have been drawing my feelings, but this may not be your thing at all.
Warm wishes
