@Blue-Blueberry Other parents have a high amount of expectation for their children and nothing ever seems good enough. This is most common in the Asian culture and are often referred as "Tiger Parenting".
Example1: Their son got A on their report card. Instead of getting praised they scolded him for not receiving an A+.
Example 2: Daughter got a degree that she likes but still, parents are not happy because it's not the course they wanted for her to take.
Although this type of example may not be true for most but the concept of it is very commonly practiced. Sometimes our parents see us as the embodiment of their ambition. That can lead to an unfair expectations that caused pressures. One thing is for sure, they just want what they think best for us. If you have done your best, if you really did- you just have to think of it as they love you enough and they want you to become better version of yourself. Perhaps, there are actually "mean" parents existing but you have to deal with it. You know what's right and wrong already and you know what to believe in either. If they've badmouthed you, never take it seriously and prove to them that they're mistaken.Show them that you got something for them to be proud of :)
Hey! This is just part of growing up. This too shall pass and this part right now you are experiencing is just a training ground for you thrive in a real outside world. Take all the voices in your head into writing, that's a great mantra to soothe your soul atm. Distract yourself in a good way and cheer up! Everything will be alright at the end. :)
