I have a problem, but I don’t know that is a problem or not.

I had to always quarrelled with my parents because I can’t give my salary enough to them sometimes. I am the eldest sister and I know I had to support my whole family. My two younger brothers can’t yet support.
Actually I have some debts for other reasons. I had to pay for it and I gave them some of the money I left. They are not happy with that money.

And my father always grumbled about this. So, I shouted out back. I know that is not good. I don’t want to mean it. But I can’t control my mind. So, my parents are sad. I am sad too. I don’t want to tell like that. But I always shout out back to them. How can I fix it?
