Welcome to the teaching world @ApricotJam ! I'm a teacher too, so I know what it is to front up with a smile on your face, teach the whole day, then run home a mess....
I wish there was more support for teachers. I have a work colleague who was going through a terrible time at home, ended up hospitalised, and in hospital continued to teach online because she "didn't want to let the kids down". I cried when I heard this. It's not an easy occupation.
I think I can go on forever on this topic, but moving back to therapy for emotional regulation. My therapy was MBT - mentalisation based therapy. It is relatively new and I guess hard to access. I completed it in Melbourne through Spectrum (a specialist service for personality disorders). Unfortunately, it is extremely difficult to access Spectrum's services. Due to the intensity of the treatment, a maximum of only 45 patients go through each year.
Looking back, MBT was the basis for which I developed a new way of approaching challenges. Instead of lashing out and harming myself, I gradually learnt different ways of thinking so that situations did not stir up such intense feelings and emotions. Previously, SH was the result of me not being able to communicate all that was bottled up in me - the pain, anguish, trauma, and frustration.
MBT gave me practise in communicating during group therapy. Over the course of 18 months, everyone spoke whether they wanted to or not. Speaking and communicating was like having a pressure valve release. The more I spoke (in this safe environment), the more the pressure was released. I think that's why I no longer felt the need to SH.
Moving on, I sure hope your EMDR therapy works. But like many therapies, people need to know recovery requires a lot of work on the consumer's part. It's not easy, and no magic pill will declare you "recovered for life".
Looking to hear from you,
BPDSurvivor
