Hi !!! Try not to freak out too much, you're through the worst if it (and the web is great for information, but scary too.) - usually HPV+ cancer responds very well... Have they biopsied the node? you have to heal of course but a neck dissection though not easy post rads - is possible. But your body is just now beginning to recover so give it a bit of time. Were you at the cancer center up on the mountain? (I'm from Toronto, but my mom was treated there for her lung cancer). I'm surprised they didn't determine your HPV status prior to treatment. There is often a difference in how HPV and non HPV cancer is treated.

Keep chugging away at the ensure - it kept me going for the few weeks I wasn't able to eat. I would worry about the past what's done is done no point in beating yourself up over it. I'm a non smokin, non drinking, non drug doing, vegetarian - and I still ended up with cancer. Now I'm doing whatever I can to stave off a recurrence but there are no guarantees. I too ad a sensitive area on my tongue from rads - it still has its moments when it spends too long rubbing against a molar. This is par for the course.

Welcome, sorry you have to be here. Rest up, and try to heal. It takes a while but you'll get through it.
