don't let the injury get you down! keep doing upper body lifting -- seated OHP could be good, and beach work. i bet that'll help, i always feel more swole and awesome after i do curls and tricep kickbacks, even though i know my arms are nothing to write home about. and keep up the pull ups, obviously. you can also do core stuff, russian twists, bw reverse hypers or supermans, any kind of crunch variation. and band pull aparts. get the juices flowing, be doing SOMETHING. it'll help immediately and down the line.
but good call to stay off it and let it heal. and i hear you on being crestfallen, that's really the perfect word for that feeling. in the immortal words of bill clinton, i feel your pain.
