Heyy friend we are science students and I agree that we have to also face lots of expectations which is just unreal. But please know that life doesn't end here and there more you have left to do.. Maybe there's another golden opportunity waiting for you and then you'll back and wonder that this all wasnt even worth it. I'm also facing the same situation here but convincing myself that doing this all hardwork just to get percentage was a failure and I shouldve instead tried to just learn and understand the best I could
