Flu after 2nd session

I just completed my 2nd session of EMDR therapy 3 days ago. We targeted a pretty intense memory of mine. I was very cool, calm, and collected during the session. Almost to the point where I thought we didn’t process it deep enough. But within an hour I was having intense physical symptoms. Dizziness, brain fog, nausea, migraine, intense body aches (mainly in my pelvis and legs). For the last 3 days, I’ve been battling these symptoms and added in VERY frequent bathroom trips and zero appetite. I literally feel like I have the flu minus the fever. My husband and son aren’t sick so that takes away the thought of a poorly timed virus.

I also want to add that I didn’t cry at all during the session, but when I put my son to bed that same night, he was laying on chest sleeping and I became overwhelmed with emotion and started sobbing. But it was happy tears? Like I was so grateful that this was my life and I have an amazing husband and son. I haven’t sobbed that hard in awhile.

Has anyone experienced something similar? Or has anyone felt physically ill (like more than just the normal dizziness and fatigue)?
