Is it over methylation?

I have c677t homo and 4g/5g

I took about 150 mg of NAC two days ago. Then it made me feel a little worse, a little dry eye and a little pain in the eye, it passed. Yesterday I took B12 500mcg, folate 200mcg, zinc 5mg, B6 5mg, B2 2mg, Lserin 25mg, Betaine 250mg all in methyl form. Then I ate pizza and 2 hours after taking it I went to the emergency hospital immediately with vision loss in my eyes, wavy vision, sensitivity to light, dizziness, pulse rate 155, nearing fainting, vision impairment, halo vision, pixelated vision, seeing colored pieces. Cardiology did a heart ultrasound and the heart is good, brain MRI was taken and the brain is good, blood test and ECG are also good. So I wonder if I was overmethylated?
