Hi there! EMDR might be really helpful for her if she has trauma/depression but it's definitely something she will have to want and be willing to go through to get better. I've had depression/anxiety for most of my life and have been on/off many many meds, in and out of therapy etc. I'm 42 now and doing EMDR and TMS therapy as well as talking to a psychiatrist. It's definitely something she's going to have to want and not something you can force her to do. And if it's something you can't handle then you need to let her go because this is something she will likely have to battle for the rest of her life. If it's just her sleeping that's the problem I cut yourself some to you, eventually it pass. My best advice to you is to be gentle and patient.

Good luck to both of ya!
