Mono related issues?

I’m 5 weeks out from my first day of symptoms. Thankfully, the worst is over - fever and tonsillitis were horrendous and lasted 3 weeks. Worst sickness I’ve ever experienced in my life by far.

So, I’m 2 weeks out from when my main symptoms fully subsided. As everything else calmed down, I experienced some GERD symptoms, which I attributed to the excessive amounts of ibuprofen I took for weeks. I then had some other GI issues but that has all cleared now as well.

Now, I’m experiencing things like: joint pain, brain fog, itchy skin, trouble sleeping yet very tired, anxiety through the roof, trouble focusing, and derealization. I feel like I’m going through the motions of life but not fully “here”. Also, my spleen is still swollen to the point where you can see it poking out from my rib.

I have an anxiety disorder + OCD so I’m wondering if the mental health stuff is just being exacerbated by such a stressful experience or if it’s related to mono? Or if I just destroyed my gut health with antibiotics (misdiagnosed at first) + excessive ibuprofen + steroids?

Anyone else’s mental health issues ramp up after mono?
