Let me break down the realities of medicine in england for you to help.
You will be giving up a lot of social life and be stressed for the next 12 years of your life. You will have to move around the country after medical school. You will have 5 years of exams at uni. Then 2 years and more exams to get into specialist training. Even if you do pass your exams, you might not get what you want as a specialty or the location you want to do your specialty. So more moving around and breaking ur relationships.
Applications for being a heart surgeon is currently at 35:1 so u really have to be the best for some specialties even gp has a competition ration of 3:1. After getting into this training u get to earn a glorius 50kand will be sitting on this 50-80k pay for the next 6-8 years. This is all done under the assumption you pass first time. If you dont then more years added on where ur earning 40-60k doing night shifts and 60hr weeks to survive. Whereas your friends in finance or computing might be sitting on 70-90k after 5 years in their profession, living where they want and doing better hours than you.
Don't go into medicine unless you are ready.
