Sometimes in life you meet people that suck the life out of you. Unfortunately sometimes those people are family. Maybe you can work through these problems with them, but I’m not sure if it would be worth it. They have already betrayed the point of family: to love and support each other in even the most trying of circumstances. It is reasonable for your parents to express that they are disappointed in your choices, but trying to punish and shame you and make you miserable is vindictive and immature. I don’t think there is any hope of a good relationship with your parents, so it’s best to save your mental health and leave. If in the future they change their ways, they can contact you and apologize.
