Ketamine vrs Psylicibin

Hi all, I apologize if this is the wrong sub to ask this. I tried posting on r/shrooms but didn't get any responses. Disclaimer: I am NOT planning on combining substances, just looking to hear from people who have experience with both substances separately.

I've been taking prescribed Ketamine sublingual for going on 3 months for treatment resistant depression and chronic pain. I've definitely had some transformative experiences, but I'm kind of stuck in this current depressive episode. Before you suggest it, yes I do all if the non drug treatments including therapy, walking, spending time in nature with my horse, clean, high protein diet, sleep schedule, writing/journaling, time with friends and family, church/Bible study, and individual and group therapy as well as antidepressants. I've been looking into psylicibin (sp) and its effects on depression. While Im not expecting a cure, I am curious if it could help me get back to baseline, or at least give me some additional perspective. I have 6g. I'm planning on taking 2g for my first time. I'll be at home with my husband as a trip sitter. I'm very familiar and comfortable with k but never tried shrooms before. If you have experience with both, how would you compare the experiences and after effects? Is 2g a reasonable starting dose? How crazy do the visuals get? Is it intense hallucinations or more visual distortions but you're still aware of reality? I want to be as prepared as possible and I'd appreciate hearing from those who have experience with both Thanks!
