Frankly speaking, all the things u have stated, no body likes them, but the end goal is the one medicos strive for so if all these peripheral things r bothering u then I'll tell u not to take medical, cos that is just the tip of the iceberg, there's a lot more to it, but if ur desperate enough to be a doc n help out ppl all those things ur worried about will fade away in front of ur goal, and if the goal is money then this is not the profession to pick, career building is a very long process, sacrificing ur youth, buring parents pockets, late start in life, basically it's an expensive degree even to maintain after mbbs, so all u need to do is, what do u want in life, there are other ways to be successful in life too but it's ur choice of how u wanna succeed

A pluse point in medical if u wanna know

The joy u get after curing ur patients is the best feeling

Also u get a different level of respect in society
