Can I become a good lawyer?

I am going to study law in university this coming September and I've recently (for a few months) been in doubt whether I'd actually make it as a lawyer. I have a few worries including:
1. For starters I've always been good at the sciences and maths and English has always been a weak point. For a long time I was contemplating medicine since my parents wanted it and I was strong in the subjects (it all came naturally) but I really dislike the thought of the long journey, the environment, the daily life just doesn't appeal much to me and them pushing it too much also turned me off. Also I prefer subjects more intellectually stimulating and problem solvy like physics and maths compared to heavy memorisation in biology. Chemistry was a mix so I quite enjoyed it but not as much. Same with stem, I don't really like the thought of engineering as I don't like creating stuff or understanding parts and maths and physics felt a bit too general of degrees, that my parents would for sure not let me do. So in conclusion my first point is that I feel I would be fit for and be able to excel in the above subjects mentioned and dont want to feel like im wasting my potential.
2. As previously mentioned English is a weak point of mine (essays in general) and law is mainly essay writing. I say it's a weak point but in both NAT 5 and higher English I got A1's (just barely because I was lucky with what showed up in the exams). For this reason I do think I'm good enough at essay writing but not nearly as good as I am with the sciences. Is this a reason to not do law?
3. I'm a quiet, shy person in general. I'm not argumentative at all which I've heard is a good trait and I'm not out spoken which helps to stand out. I honestly hate to start arguments for the sole reason that when I do argue I never feel confident with the knowledge I have. If I haven't done prior research I'm the type to not just say what I think. Unless I'm sure that there's evidence and it is properly backed up I hate making claims. I also much prefer looking up and weighing both sides of the argument before making judgements so that I can be completely truthful and unbiased. For this reason I tend to not start arguments ever as I'm never able to trust what I know as fact or perhaps the random false article I read. I've also been raised in a household where being wrong is punishable so I'm the type of person who very very carefully, and usually not confidently, make judgements and give answers. I feel like some of these traits aren't the most suitable for this profession so I would like to hear your thoughts.
Lastly, the reason I chose law (apart from the money) is the daily life, and it's intellectually stimulating course work. It may not be maths heavy but it's problem solvy in its own way. I also find learning about the rules and regulations we live by to be super interesting, I really consider knowledge as power and feel it is a super interesting subject to understand our society. I may not be good at essay writing but in this past year taking advanced higher English (maybe I failed) has really helped me open up to essay writing. If anything being able to write fluent, clear essays is a goal and something I aspire to do now! I did two short work experience opportunities and really enjoyed both of them and there are many areas of law I am interested in and want to learn about. I tend to never be able to make decisions which I believe isn't the best of traits to have but I have confidence that I will be able to improve those parts about me in the future. Taking all of this into consideration, I would love to hear your thoughts on this subject. Thank you
