My mom is diagnosed with Ischemic Brain Stroke.

I don't know how to prepare for exams now. This happened today at 1 pm-ish time when she collaped by herself and won't communicate with us or make coordinated movements. We thought it's just weakness or low blood pressure, but later we found out it's Ischemic Brain Stroke, which means that arteries leading to the brain are clogged, causing severe coordination problems including not being able to talk, understand or take decisions.

The day was really difficult. I had to keep my mom by my side during all types of painful tests and the fact that she couldn't speak or make her points broke my heart. I really wanted to break down and cry so many times but I couldn't because it would stress her out and unfortunately deteriorate her mental condition even more.

I don't know what I'm gonna do from here. I can't study with my mom in the ICU and my dad being by her side at all times. The possibility that she might never be able to be the same is haunting.

Why did God do this to me?
