Making a negative dua when someone hurt your feelings

Assalamulaykum, This is something that has deeply disturbed me. There is a Hadith that there is no barrier between the dua of the oppressed and Allah so that means that dua will be accepted. There is also a Hadith that says do not duplicate for yourselves anything but good for the angels say Ameen to whatever you say. In light of these 2 Hadith I have now become very fearful because once a really close family member hurt my feelings by making fun of me and saying mean things. Then I made a negative dua for them. But that was just because I was angry in the moment and now I feel guilty. Because I was oppressed at that time because their words hurt my feelings and because angels say Ameen to whatever one says for themselves and their family, due to this I’m really scared. Please tell me what I should do and if such a dua comes true by default. Such disputes are normal between families so I hope my dua is not regarded as the dua of the oppressed.
