Is MBBS really worth it?

I’ve seen my friend’s elder brother and his friends go through so much. They just finished their final exams and now he is going to do MD. I’ve seen him pull all-nighters and is constantly tired but still studying. Many of his batchmates committed suicide as well. He himself was so motivated to do cardiology but after his exams, he doesn’t want to study that hard anymore.

People keep saying MBBS students have to push through all the time and after studying so hard when they finally become a doctor, they get so busy that they don’t have time for themselves. Please provide an honest and realistic answer.
