How long have you been feeling this way / when did you use the field?
I don’t have much experience with Morpheus, but reading the description on YouTube it doesn’t sound like there’s anything that would directly cause what you’re feeling.
It’s possible that it’s a form of detox? If the flush worked as described then I imagine it’s clearing out a lot of negativity from your mental and emotional bodies. So it could be a “things get worse before they get better” reaction.
Either way, I think these would be safe and helpful:
-Grounding and/or Schumann Resonance
-Energy Body / Aura Deep Cleaning Clearing
-Clear All Negative Energy and Entity Removal
-White Light Waves
-Angelic Intercession (ask them to comfort and protect you, and maybe to gently speed up your recovery to “normal”)
-Amygdala Healing
And throwing this one in here just because it’s a recent favorite and an inexpensive paid field:
-Alchemical Ruby and Carnelian
Best wishes!
