Stool problem facing very much. Do i do.

Hello doctor, Mera name Mohit soni hai and i am 19 years old. I started this problem since Lockdown started.When I take food, it goes from stomach to intestine to digest but then after that it does not  goes from intestine to the bottom intestine or a large intestine. And neither do I feel the pressure, because of this I do not get potty for 3 to 4 days.So I have to drink a medicine 3 spoon so that the stool becomes like a loose motion.And because of the lack of potty, I do not feel hungry. The gas passes from stomach only.So I sometimes feel that there is a block somewhere in my intestine and but when I take medicine, after passing the stool it seems that there is a no block.When I do not get potty for 3 to 4 days, then I drink hot water again, which keeps it thin inside the intestine, which is a little bit closer pass stool.That's why i can't eat anything So what do i do.
