I agree with BuildAbridge. Great advice.

I don't know your country, but here in the U.S. we have thrift stores where I buy nice used clothes and other household items such as furniture.

I'd say help your parents some, but it does sound like they are taking advantage of you. They won't be happy with you, but, as you say, you do need to consider your future.

My husband and I still help our sons (23 and 24 years old) financially. They are both in graduate school and work part-time. That might be more of an American thing. We are blessed to be able to give to them and still live comfortably. We save money in all sorts of ways.
