That is not weak!
I email my T CONSTANTLY every day. She replies as much as possible. If she doesn't after a certain amount of time my mind also floods with negatives and doubt. It's something that has to be worked on in therapy. We have to learn not to think that everything in the world revolves around *us* but that they may be busy, tired, computer crashed, etc. That the good and bad in life are not because of something we did or did not do... This takes a lot of work!
Trust in your T!
