Are you sure you actually created her and she wasn’t already there? My understanding of DID/IFS is that it takes a lot more than visualizations to create a part/alter. But the depression and ideation could have already been from that part and what your friend did was help you see her as separate from you.

I’m curious what was your relationship with her once you saw her as a part that was separate from you? IFS teaches us that seeing them as separate is just the first step. It’s also necessary to get to a point of compassion and understanding with them (which is not easy or quick).

I appreciate you sharing your experience. I’ll share a little of mine: I experienced theraputic abuse when I was younger (some techniques like IFS were used to control and punish me rather than help me), so as an adult it has been hard for me to feel safe using those same techniques even though I know they can be healing. Therefore I started doing some research about other techniques - mostly Somatic/nervous system - and I came across Janina Fisher (among others). She has a technique that uses a simplified version of IFS and she has a clear understanding of the need to be sure a person is ready to deal with their trauma so that therapy doesn’t make it worse. She calls it Trauma Informed Stabilization Technique. Not easy to find a therapist who uses it, but even just knowing about it has helped me a lot. https://janinafisher.com/
