Idk if this will be any helpful but I will tell you a little about me. I started a computer engineering degree and ended up not liking it. I was debating whether switching to Chemistry or to a degree called environmental science. I ended up picking chemistry and I did pretty bad the first couple of years (I am also bad at math). I was not motivated. However idk where from but I got the strength and the motivation to start working harder and I ended up doing pretty good. Now if I think of this, I would have probably been just as happy in the other degree (environmental science) that's why I said sometimes theres not just one correct answer. I think if you put effort into something (something you don't hate) you will see nice results and that will feel motivating and will make you feel fullfilled.
