I am 20 year old male, and i am, underweight. Now I have an allergy to dairy products but in childhood I had allergy to dairy, dust, meat, masala, sweets, dry fruits etc so I have not consumed those in my childhood is that make any difference now in this age. I have a problem while applying logic in studies. I take too much time for replying anyone's answer or analyzing what to say. So every one in my friends circle tease me and I cannot response I get scared. While studying it takes too much time. I have to read those lines again and again to understand.
