I can understand your dilemma since I have known a friend who dropped two years for NEET prep.
As far as I understood seeing him, it does not matter if you’ve decided to give extra time for something you really want to have. And once you have it, it is going to remain with you for life. Worrying about what everybody around you has to say should be the last thing on your mind. You just require preparation in the right direction and your parents blessings because they are the ones who deserve more happiness than you do.
My friend got selected after dropping for the second time, that too through Haryana quota where cut offs go high every year. Another guy who was an acquaintance of mine got selected in AIIMS Raipur after a drop year!
Many examples. Focus on the more positive ones.
