I have a question regarding fasting.
I feel strain in my kidney area during fasting. Also, I have a target of sitting for GRE exam in the last week of June which is being seriously hampered by fasting as I can't study while fasting as my brain doesn't work (I can't focus) when my stomach is empty. Also, it creates problems in my daily routine. I already have insomnia for which I am taking medications.
But, I am scared of skipping my fasting in Ramadan as it reminds me of death and afterlife.
Is there any way I can legally skip the fasting in Ramadan? What does Islam say about my problems?
