Hey 3 attempts are no biggy at all, I was successful in my fourth attempt.
1st attempt – Aiims rank unknown
2nd attempt- 6000 A.I.R
3rd. Attempt- 300 A.I.R
4th Attempt- 49 A.I.R
I still remember ,I cried when I saw my rank on screen the fourth time and my parents were surprised as to why did I cry, I cried because I felt this repetitive cycle of giving so many exams stopped and this was MOKSHA….unlike you I had no responsibilities and my parents were immensely supportive ,but I know many others at AIIMS who had to manage responsibilities and repeated attempts.My advice would be
1) Try explaining the situation to your parents most of the time they do understand.
2)Try giving upsc( union public services exam) ,if selected the salaries are quite good(especially after the 7th pay commission) and work is not that hectic i.e you can work and prepare for pg entrance with no stress.They also give you leave for completing your p.g
