Hi @krob and welcome. It looks like your husband is getting great care, particularly with proton radiation which is far less evasive than the photon mess so many have endured, myself included.

Hello Robin. I too came here in January for support with my diagnosis of P16SCC. Right now I'm about 10 weeks out from surgery. It really is helpful to visit with people that are in this same struggle. The physical aspects are one thing but managing the mental is another. I understand about friends. When my diagnosis first came out, people were shocked and all over us. Now a little time has passed and people have moved on which is natural. The best advice I can give is stay close and talk. At the same time, caregivers sometimes need a break. My wife has friends and sisters she can vent to during those tough times. People said to me in the beginning that this is a journey and not a destination and boy were they right.
