Dude come on. Buck up. You are a MBBS doctor now. You have a graduation. And luckily in medical field atleast in India there will always, mind you always will have a vacancy of doctors everywhere : GOVT & PRIVATE.
SO GO OUT OF YOUR HOME AND WORK.
If you are staying in a village area then also start your own practice. You will not get patients until the word spreads that you are a doctor.
Take reasonable fee from reasonable patients.
Earn on your own. Fund your own coaching. Study on your own money.
In this way even if you are not able to crack it in first attempt, you won’t have any guilt or mental pressure that you have wasted someone else’s hard earned money on nothing.
