Why do I never feel good doing DXM?

Don’t tell me to never do it again because I already lost interest lol. But can someone explain to me why I never saw visuals, nor dissociated or anything?? I always feel sad doing Dxm and sober asf😂 Although I once felt kinda drunk doing it but the giggles weren’t there. And I do feel robotic (robowalk) but still sad and not high or as if I’m on drugs. I rarely do dxm
