Parents will always see you as their baby girl. They knew you while you were still wearing diapers and suddenly you are a big girl with makeup, hugging a stranger. It’s a shocking shift for them so overreacting is quite understandable.
Try to stay calm and talk about how it affects your feelings. You must draw the line and let them know if certain behaviors are not acceptable. Ultimately, you’re the one who decides who you want by your side in life.
