I only get to see my t once a month(unless theres a crisis)
Ive found it really hard with those bad times in between sessions.
One suggestion is-make a list of stuff you would like to do or accomplish over the summer.That could be fun stuff or chores/jobs around your place./exersize plans/ etc.....Make time for a real holiday of some kind too......everyone needs a break away from the mundane.
I find journaling to help get through difficult time lapses in sessions as well.
Good luck,stay focused on staying healthy!

ps-If your T says you can e-mail her.....dont feel guilty.
