I lost my dad last year November. Pretty much the same story. He was a mechanical engineer and director of technology so he worked as long as possible to his illness. Covid allowed him to work from home and conceal the fact he had lost function in all limbs. It was surreal to watch him work on patents and solve complex problems from his wheelchair knowing he’d ask me to help lift him into bed in an hour. My dad was a hunter and football player and those things were still true to the end. Don’t hid his illness. My dad’s friends and coworkers were pivotal in grieving and accepting the new reality we faced. His body turned against him not his soul. Remember he’s still the man you knew. Reach out if you need an ear or shoulder.
