TITLE: Me (23f) with my therapist (30?f) and her departure. [non romantic]
POST: I hope this is the right place for this but I figure a professional relationship with questions is still a relationship with questions. I wrote this on mobile so please excuse spelling errors.

I have been in therapy for many years (mostly for depression, anxiety, and my personality disorder). I've been seeing my current one for 2ish years I believe. She (30?f) has been very helpful and warm which is a stark contrast to one I had prior to her. 

She's been very open to me and we have a friendly relationship and I genuinely follow and enjoy her insight. I find a lot of her qualities are like my own and believe in another life time we would've been friends. She's leaving this position really soon and I'm having trouble with that? I've jokingly brought up staying in contact but I am shy because I know it's inappropriate. She's a social worker, which is exactly what I'm in school for and these sessions have not only helped with my poor mental health but quelled some fears about my future career. It's hard because I see her as a bit or a mentor as well as my clinician so to let go of that relationship. 

I know it's my own personality disorder that may be making it hard for me to let go so I know I shouldn't pursue an inappropriate relationship and ask to remain friends. Has any one else been through this? How did you cope? did you remain in contact? was it easy to move one?
TL;DR: 
I grew quite see to the guidance and companionship of my therapist however, she's leaving so I have to figure out what comes next.
