In my experience, being one who avoids contacting T outside sessions as much as I can, contacting T when I'm in a bad place is extremely helpful and tends to reduce my obsession w/T...or any issue taking place between us. Some Ts believe allowing contact (whatever that may be: texts, emails, calls) builds trust, encourages a positive alliance and attachment experience for the client. I understand Ts not wanting to have a whole session by text or email and wanting to limit contact to emergencies or brief assurances. Maybe you could talk to your T and ask her to give you a better understanding of when it's appropriate for you to contact her out of session...?
