If you find it difficult, rather than talking about the emails why don't you ask her to teach you ways to cope with your stress. For example journaling, mindfulness, DBT skills.

By learning new ways to cope into ground yourself when you are stressed to the max you'll eventually be able to calm yourself and not have to send so many emails.

Sometimes wonder if therapist who allow all of the excess outside contact get a high from having their clients dependent on them, or if they simply don't have any other tools to teach their clients to live independently. From reading these boards it appears that many therapists enable an unhealthy dependency on them. This doesn't help the client deal with everyday life on their own which ultimately should be the goal of therapy.

Good luck with whatever you decide and I hope your stressors will start to subside this year.
