Stressed and worried about school and family

Having just finished finals, I know for sure I failed one of them which may completely kill my grade for the class and end up putting me on academic probation or even disqualification. I am worried about how I will tell my parents since they are very strict and focus a lot on my education, but I am miserable since I feel like this major isn't for me and I was already thinking of changing it after this semester. I have no interest in most of my classes and it's making it so hard to focus in them. In the beginning I was able to keep up and work hard but after a while I was lost and too scared to reach out for help. I just feel so bad since I feel like I've failed my parents and did not live up to their expectations but I'm more worried about how they will react. I've told them I was doing well but with online learning and being home since the pandemic, they are constantly looming over me and feeling burdened both by my failure to do well as a student and as a child. College was the only real goal they set for me and here I am almost being kicked out in my first year. I would appreciate any tips on how to break the news to them as well as any advice for moving forward.
