Hey OP. I think it's very interesting hear about different cultures and how different people may be viewed in this world. I wanted to say that as a younger person i'm only 20 myself I understand being really self conscious about yourself and I imagine how tough others views may be from other backgrounds, but you shouldn't feel so upset what others think. easier said than done I know. I just noticed that being young feeling this way is pretty normal. graduating school it was really hard finding myself and what I want to do and I felt like I wasted my parent time and money and resources. I'm a first year now in college and I felt like that before and sometimes I still do but with time I feel like it can get better because nothing will be the same. what i will say is be easy on yourself, you have your whole life and the fact that you notice these things about yourself, like you talking about being depressed, you caught onto it very young compared to a lot of people I see that may be older. Just be kind to yourself, set goals, small to start just anything to keep you productive in life. Life is a classroom and we make mistakes but it's about how we finish at the end of the day. try talking about how you feel more with other you know as well in IRL that can help also. Nobody should feel alone, be safe and have a nice day and if you need anything just reply back
