I feel insecure because of my sister :(

I don't feel good enough or pretty enough because of my sister. She's extremely beautiful and whenever our family friends come over, they gush over how pretty she is. I never get compliments from them and because of that, I feel like I'm not good enough. My sister is the whole package and now she's engaged. I on the other hand feel like I'll never be engaged and that nobody will ever love me :(

I feel like part of my insecurity is because I can't really be who I am with me having a sister who is perfect. My mom always compares me with her and whenever my sister gets a new job or a new style my mom expects me to be like her. It's like I can't be my own person like I'm living under her shadow :( I want to move away but I feel like this reason would be a ridicelous reason to move away once school finishes
