I took a riba based mortgage when I wasn’t practicing Islam

As-salamu alaykum. I want to start off by giving some context to my situation. I am a revert that lives in a non Muslim family. For some reason my parents are heavily against me being a Muslim so for the time being I am practicing in secret. My parents have been pressuring me and my brother into buying a house under me and my brother’s name for almost a year now. About 5 months ago I caved in without thinking of the consequences and went along with what they wished and took a riba based mortgage. My parents helped with the down payment contributing 150,000 dollars while I made a contribution of 23,000 dollars. At the time of this taking place my faith was very weak and I was not practicing Islam at all. I wasn’t praying, reading the Quran or doing anything as a Muslim. Alhamdulilah, recently I have found myself faith again and I have realized the grave mistake that I have committed. I would really like to hear some advice as to what I should do because this is really bothering me.
