Hello there.
Firstly, you have absolutely done the right thing. Anyone in any kind of predicament like this and my advice would be to suspend studies. Sometimes life gets in the way of study- it's no big deal and it can happen to people. You suspend until you feel ready and able to come back. Live your life, learn to drive or whatever, come back in September or even wait until September 2025. It is no big deal.
Forget your age- it's just a number and there are thousands of people of varying ages in medical school in the UK. The fact you are one year older is of no consequence.
Focus on your health, forget the course for now. By the sounds of it you could have persisted with the first year but what if it had ended in a flaming wreck in July? You'd have to have repeated year 1. This way you get time for yourself, you can recuperate, relax a bit, go and do some healthcare work, reignite your passion for medicine and come back. You'll know what to expect and in the meantime if you want to look at some of the course content and start learning it in your own time and pace, that will help when you return also. Some people do this, some don't.
I totally and absolutely understand your situation- believe me- because it happened to me as well. It happens to people and it isn't anyone's fault. There is no need to panic.
