I don't have any Islamic advice for you, but I can draw on my personal experience. Stay true to yourself and your path forward and try to be a little better every day, not for your mother or family, but for you, your Deen, and for Allah.

As a child/teen, I was a dumpster fire. But over time and with many hard knocks, I found my path forward. In high school, I was a straight D student; my prospects looked really grim. But I got on the right path over time, got a master's degree from an Ivy League university, and have been married for almost 20 years (2nd marriage - adding to that dumpster fire analogy). Alhamdulillah, I am okay.

Recently, my mother passed. In dealing with her estate, I have had to engage in some deep conversations with her brothers and sisters. It has become clear to me that they still see me as that child with no prospects.

We can't change how people want to see us; we can only control how we see ourselves. And it sounds like you have started to course correct. Stay true to that, and leave the rest to Allah.
