I sent something every day. Sometimes it was a long, chatty letter. Other times I photocopied his favorite comics (Calvin and Hobbes). I sent newspaper clippings of community events. Once I even sent an envelope full of dog hair so he could sprinkle it on everything so the place could feel like home! When I was at the beach, I mailed sand. I never said anything that would make his CBT more difficult (I miss you, wish you were here, etc...). I tried to stay encouraging and upbeat. I also didn't tell him about things that would make him feel sad (we had a great big party and everyone was there...). When he went too long without writing, I mailed him form letters w/ stamped addressed envelopes. He only had to check the appropriate boxes or fill in the blanks. I know the letters meant a lot to him...he didn't always have time to read them, but enjoyed having them for when things settled down.
