I am 15 years old. The only person that ever compliments me is my mother, and I never get any compliments from anyone else. Is this normal?

It’s understandable to feel concerned or self-conscious about not receiving compliments from others besides your mother. However, it’s important to keep in mind that everyone experiences different levels of validation and acknowledgment from others, and it’s not necessarily indicative of your worth or value as a person.
It’s also worth considering that people may express praise and appreciation in different ways, and some individuals may simply be less vocal with their compliments. Additionally, in today’s society, people are often consumed with their own lives and may not always take the time to show appreciation to others.
However, if you feel that you are not receiving the level of validation and support that you need, it might be helpful to seek out activities or communities where you can feel appreciated and valued for your talents and personality. Surrounding yourself with positive people who recognize your strengths and offer constructive feedback can also help boost your confidence and self-esteem.
