pay it if you owe it, take responsibility for your own actions

My father passed away three years ago, and to save the debt my father had taken for that work, I borrowed money at 10% interest. I gave them only interest for two years because even though I made money from the cake business I was doing, it was difficult to bear that interest. Later, I talked to them and reduced it to 8%. I still give only interest because with the current situation in our country and the expenses at home, it is difficult to do so. Now they are asking me for money all at once or they are scaring me by saying that they will go to the police. Help me get rid of this debt.
