Yes, apart from fatigue as things stand I have overcome all symptoms with the help of medication. I have recently overcome headaches as well with the help of medication.

I have no issues with sound now, I used to struggle with severe noise sensitivity, hypercusis, struggling with louder noise and multiple conversations. I used to have to lie down with severe fatigue after experiencing noise or being overloaded during the acute phase.

It can be overcome but it took a long time, personally I used earplugs when outside, but restricted noise. I really got better when I cocooned myself from other people and my family, taking quiet rest and spending time alone. Then I got back to working in a stressful job with a phased return to work. Good luck with overcoming your symptoms, it can be done!
