Hi Ed - I'm sure you'll be hearing from a lot of people here who have had direct experience that resembles yours, so hang in there. Stay optimistic and don't think about the negative "what ifs". It's good you already have the Ativan to help with the anxiety of being in the mask. When my son had his Rad TX, they allowed him to bring his own music and they had other music they could play while Rad Tx was going on. Listening to something helps to let you know how much longer you have to go before you're done. Just let the doctors know about your anxious feelings and they may be able to reassure you.
