Should I do medicine at university?

I need help choosing a career. I have no idea what I want to do in life because I would do alright in almost everything and I don’t feel a particular passion for anything. I do love English but I would much rather get a qualification that has some sort of job security, and I enjoy learning in general so not studying English isn’t going to make me hate life or anything. Me and my mom have been discussing it for ages but unfortunately for me, she’s an incredible parent who refuses to push her personal desires onto me so I can’t even just do what she wants. I settled on accounting for a while but the university I want doesn’t do a specific accounting course. Like I said, I’m not really passionate about anything so I had no qualms about discarding it. I’ve since kinda decided to go into medicine because it’s a good, respectable career and one that I can hopefully make money in. I do also enjoy social interaction and I’ll be glad to make an impact on people’s lives but it’s not like it was my main reason and that’s where I’m kinda struggling.

People have spent their whole lives wanting to save and help people, and working up to become doctors. It feels kinda unfair and even rude to pick the same career on a whim. This post makes me sound heartless but I do genuinely care for others and it’s not like I’m just in it for the money, but I need to live comfortably. I refuse to let all my mom’s sacrifices go to waste and I want nothing more than to repay her and pull us out of poverty so at the end of the day that is my main motivation and the root of my second issue.

My second problem is that I’m not sure if doctors are that well paid anymore, or rather I feel like there are much better professions for making money. A lot of doctors talk about how they think the job is worth it despite the long hours because of the difference they can make. I love helping people but I don’t think it’s worth the heavy debt of university and the stress of doing medicine if at the end of the day I can’t even pay my bills.

At the end of the day I guess it all comes down to money. I’m in year 11 about to do my GCSEs (it’s unlikely I’ll get less than an 8) and I’m asking now because I’m picking my A-level subjects so I don’t want to screw myself over with an incorrect choice. Right now I’m thinking of picking Biology, Chemistry, Maths and Psychology but with some luck I may be able to swap Psychology with English.

Sorry for the long post and thank you in advance for any responses. I promise I’m not a bad person I just want to be honest to get relevant responses
