Longing for justice as a child of abusive parents

Salam everyone. I grew up with an abusive parent. Ever since I was little, my parent has constantly cursed me and called me the worst names. It's made me hate myself so much that I truly believe I'm terrible and don't deserve any good in this dunya. I know our deen tells us to be dutiful and kind to our parents, but I keep hoping there's some fairness for me too. The abuse pushed me to self-harm and even made me doubt my iman at times. My parent prays all five prayers and seems more practicing than me on the surface, so does that mean I have no right to justice? Is it acceptable for them to curse me and say I don't deserve happiness, friends, or a spouse? Just to give you context, I'm 29 now, and this has been going on since I was around 8 or 9. I'm completely drained.
