Are these wise UCAS subject choices?

I know this is a long post so in advace i would like to say Thank you to anyone who takes the time to read this all and respond.

When I was younger (from early childhood until sometime towards the end of fifth year), in my mind all I was going to be was a doctor. My father really kind of overestimates my intelligence and ever since an event that took place when I was like 3, where as a result, I said I wanted to be a doctor it was all he ever encouraged me to do so I never really considered anything else. He always talks about how he always knew I was the "smarter" twin and always emphasised how much money doctors make which was a big pull factor for me (the main one I think). I think he did this because we are not well off and he just wants to see me be successful; I would be the first to go to uni if I do.
I started to doubt my ability to get the GCSE grades and my personality suitability because I vomit every time I see another person do so. I never ended up getting the necessary straight A's and A*'s anyway so becoming a doctor now is out of the question but ever since I have been uncertain of my future as for the best part of 12-13 years I put all my eggs in one basket. I also often find it hard to motivate myself to study.
I repeated lower sixth and dropped biology for psychology because I got a U but I hated biology anyway and only had it as a third A Level. I got an B in maths first time and brought it up to an A by repeating one module. I got an E in physics and brought it up to a C on a new specification where AS accounts for 40% of A Level (I was 2 marks off a B). (I got a B in psychology.)
The courses I was going to apply for are Mathematics, Physics and Applied Mathematics (both at the same school at the same uni), Energy (where you learn about renewable energy systems- a 2nd uni), and Aerospace Engineering (at the engineering school in the first uni) because I think it would be cool to spend a career making things that fly (I did a 5 week placement at a bus company so I have an idea of what engineers do). The grades these courses ask for range from ABB to BBB.
The first three courses are science degrees so I don’t know if I could write a personal statement that is also for engineering so I need advice as to whether making those subject applications would be unwise.
I am very worried that I will go to uni and it will be for nothing in the end or I will have chosen the wrong degree.
I am nervous about the prospect of moving away anyway because I am not good socially or with people (I have no friends but I am sometimes friendly with people) so possibly needing to find a part time job where good social skills are necessary and just trying to fend for myself without the support of coming home to my family everyday, is daunting.
I live in Northern Ireland and for the above reason I don’t want to leave NI (at least I would only be an hour bus drive from home).

Thanks again to anyone who took the time to read this all and respond.
