Welcome and sorry your here. Your story is all too common. I am betting on
HPV pos. Either way you get the same treatment. Not that life is not busy enough, but now you have a whole lot more work do. This winter will be a rough one. Most people get rads and cisplatin. This will make you week and tired. You will not be doing any really physical stuff come Dec and Jan. Plan ahead, do what you can now and line up help where it might be needed. I am thinking house, car, yard, work, garage, snow. For over a month I did little more than move from bed to car to couch to bed and repeat. I am almost a year out and doing just fine now.
Other will also have suggestion, but I will start with get to the dentist now. Cancer took your tonsil, do let it take your teeth.
