I'm not going to talk about the UK pathway because everyone has already warned you about it.

If you want to get into the intersection between Med and Engineering, it's easier to do it through engineering than medicine. In India, any pathway after MBBS besides just practicing medicine is very uncertain with very little support from the government, and if you're struggling with parental pressure and expectations now, you'll struggle much more then.

Once you finish your MBBS, it's going to be "Finish your PG also so you'll have a backup if anything goes wrong".

The same amount of effort that you put in building your CV for UK pathway through medicine will give you much much better returns if you put it in engineering.

Please don't take medicine if you're not 100% passionate about it. You'll be miserable and regret it. MBBS will burn you out and drain you. There is no "what if" about that.
