It's understandable to have doubts about your appearance, especially when you're living in a society where certain beauty standards are promoted more than others. However, it's important to remember that beauty is subjective and there's no one-size-fits-all definition of what it means to be attractive.
It's natural to have moments of self-doubt even when you're feeling good about yourself and if you're genuinely happy with how you look and people have expressed interest in you, it's likely that you're not delusional about your appearance.
As for the comments about your personality, it's important to remember that people's perceptions of others are often based on limited information and their own biases. If you want to focus on your studies during your free time, that's completely understandable and doesn't reflect anything about your sexual orientation.
And being a person of colour doesn't necessarily put you at a disadvantage when it comes to attracting the opposite gender. Let's put this into perspective: some of the prettiest women in the world are people of colour, for example, Zendaya, Beyoncé, Deepika Padukone, Aishwarya Rai, Priyanka Chopra, and Jourdan Dunn. They are all powerful, independent, and strong women who are not white and have different body types. They are considered some of the most attractive women in the West and in the whole wide world. Whilst, this may sound rude, which is not my intention, you are at an advantage.
So when you think of putting yourself down and believe that you are not attractive enough, remember that you are pretty and cute, and some might even say more. You could be the most amazing and fabulous person someone could meet. Don't let some silly boys in your school judge how attractive you are. Your value is in your hands, and it's up to you how much value you place on yourself.
If you still feel like you're not pretty enough after reading this, think about what an attractive person would do. What actions and practices can you implement in your daily life to get to the point where YOU feel satisfied with your worth?
And sis, all these boys will come and go. They are still very much immature. Some of them are still getting fed by their mum, some don't even wash their faces, and some are uncomfortable with who they are and are still figuring things out. Focus on yourself, give yourself time to appreciate yourself, get to know yourself, and focus on your studies and career. Eventually, the person who is meant for you will come at the right time.
At the end of the day, is what is important to focus on what makes you happy and confident, rather than worrying too much about how others perceive you. You are the only person who gets to decide how you feel about yourself, and that's a powerful thing.
Hope this helps
