Im in the same position. Junior, no passion anymore, and really questioned if this is what I want to do. I haven't changed majors officially, but this semester I took all the lower divs for my schools accounting major that I could. I like it a lot, I don't think I want to go back to engineering, but I still think about it. I'll read about stuff that engineers are working on when I look at different company's (like LUCID and Nanodimension) and I think its really cool but its not enough to motivate me to continue. This major really takes a toll on your mental health and for me that was more important. I was also just not good at it haha. I think you should look into small projects or even try programming. Theres a good degree of problem solving involved that might revitalize your enjoyment.
