My therapist encourages me to write her anytime I want or "need" to, though I don't personally see it as a need but it helps to not feel alone so much and overwhelmed as I work through symptoms, memories, day to day stressors. It has definitely helped my therapy progress faster, the ability to contact her frequently, but she charges for email sessions, so sometimes I feel nickeled and dimed for the extra contact, though I certainly don't blame her for charging! I respect her time, I just wish I'd win the lottery already.

However, she will not charge me for brief check ins, a paragraph or two, it's just I usually end up writing in depth.
