What are the long-term effects after surviving chemo complications?

In July of 2023, a biopsy of a swelling in my neck revealed that I had cancer. After returning home from a vacation that couldn’t be canceled I started chemo in mid-October 2023 and my first session went well - no bad reactions from the drugs. However, on 27 October 23, and as I got ready for bed, I coughed - and a huge glob of blood landed on the bed. From there, things were hazy for me and I have few memories past hearing an EMT talking to me and, later, someone asking about my blood type. I lost three weeks of my life; I learned that I had died twice, once from near-total blood loss and then because of hypoxia and only blood and a tracheostomy saved me from a permanent death. I still think the chemo made the tumor disintegrate. I learned that I had an HPV-related cancer. I am into my third year of post-cancer checkups and I remain cancer free but with lingering effects from both chemo and radiation.
