Then after one year he got some breathing problems and doctor said that he got blocks in heart. doctor told my husband to go for operation to remove blocks. but mother-in law refused for operation. i requested them so many time to take my husband to hospital for operation, due to financial problems and my mother-in law decision my husband operation got delay.

I am living with the hope that God is there to help me. Please help me. sorry i have written a long story to explain my problems. i am writing this in beleive that you will defenitely pray for me.
