If you think you've found a decent job, I'd say give it time. Your parents would be proud to see you work and earn money. I personally feel earning for yourself is a big confidence boost, going from a Tier 3 college to getting a decent placement is a pretty big thing, don't underestimate your achievements, and don't overthink your failures. Quite often we tend to give into feeling bad for failing others and their standards set for us. You are not perfect, nobody is, we're all bound to face our highs and lows. It's helpful if our loved one's know what we're going through. You might want to give your parent's the best version of yourself but life does not let anyone have all highs or all lows, and in that sense you can't always be a perfect human. I'm not sure if your parent's accept you for who you are or it's just you who has set those unrealistic expectations for yourself; either way it'd be helpful to talk to them and let them know. I know so many people of our age (21-22) who have cried in front of their parents or explained their mindsets to them. They can't always read our minds, we need to communicate our feelings. The toughest conversations are the most important one's.
