Hi. I'm new to this group and first time adding to conversations. But I have done EMDR and it has blown my mind. If you tried it with a therapist who got frustrated with you, then that was THE WRONG THERAPIST. I hate that for you because I understand how much effort, emotion, time, money, etc. goes into each and every type of appointment. But I urge you to continue trying to find a GOOD EMDR therapist. Another thing I have been trying this year is hypnotherapy. It may sound a little out there, but I have learned more about what true hypnotherapy can do and am so interested. I have worked with a therapist I trust (my EMDR therapist) and we've tried about four times with not being able to put me fully under yet (not reaching my subconscious). But MAN am I so interested and eager to reach my subconscious. If you're not interested in that or don't have someone you can trust (because that is an extremely important part of being able to have your conscious mind let go enough to allow your subconscious to come forward), I get it. But at least give EMDR another chance - shoot - a lot more chances until you can find someone who can truly support you with this.
The way my therapist explained EMDR to me was that we have the memories - but when our mind doesn't know what to do with them or is trying to protect us, it doesn't "file" them in the appropriate places. Think of how someone in the military seems fine, then hears fireworks and suddenly feels like they're back in battle. That's because the mind has that memory, but when certain things (sounds, smells, voices) trigger it, it just comes forward as 1000% real no matter what you may logically think or know otherwise. So EMDR helps to find those memories, thoughts, emotions and then you can address what they really were and where they really need to be filed. Once they're filed in the right place, they're not free to jump forward as reality any time they get triggered.
I hope that helps. Bottom line is I encourage you to find another EMDR therapist and keep trying. Be kind and gentle to yourself. I won't lie - it's hard. It's bringing that crap front and center again - but with the purpose to expose it, reveal it, acknowledge it, and then file it away so you can move on.
Best of luck to you.
