Yearning for the Dark Days

I noticed I’ve found myself yearning to go backwards. Back to my dark days and dark times. I know I’m better now, my therapist says it, my family sees it, and sometimes I do feel that way. But then I get that impostor syndrome, and I want to go back to where my big feelings were not belittled and actually examined and I felt like I was cared for. I don’t know if that’s exactly wrong or anything. Is there anyone I can talk to? I don’t want to feel alone anymore.
