You said it yourself that it was the same advice she would give you. Perhaps deep down or subconsciously she knows that it is right, but might not be in strong point in her life to admit it to herself much less out loud to you. If your sister is anything like mine, if she really didn't believe in the advice and didn't want to hear it, she wouldn't keep coming back to you and setting herself up to hear your advice again and again. I wish you the best difficult situation and hope that your sister will one day see the light so to speak. I hope this was helpful.
