Is it normal my mom always tells other relatives about 'bad' things i do?

Is my mother right in doing this? My skin tone is very uneven (some parts of my skin are lighter and some parts of my skin are darker) plus I have a patch of hyperpigmentation on the side of my face. When my mom saw my skin, she claimed that I was skin bleaching and she got mad at me because she thinks I will damage my skin for good. She told one of my family members that I am bleaching my face and the family member talked to me about it in a very disappointed way. I feel so embarrassed that she had to tell a family member and I feel like that family member will not see me in the same way again. I literally got so sad because now I feel like I don't have a good relationship with my relative now that she thinks I am bleaching my skin. Now she might see me in a negative light as an insecure girl wanting to conform to standards when I should be focusing on my education instead of what my skin looks like. I feel like it would be awkward being around that relative now that she thinks I am bleaching my skin.

I saw a dermatologist and she told me to use hydroquinone only on my hyperpigmented patch of skin on my face and that is what I have been doing. I am using glycolic acid products on the other parts of my face that doesn't contain the hyperpigmentated patch of skin to exfoliate my skin and make it look less dull and more even. My aim is not to bleach my skin but for my skin to look good (even toned and not dull) without wearing foundation but I feel like my mother does not understand this.

My mother really ruined my day because I hate it when my parents tell other relatives about my insecurities or all the wrong things they think I am doing even though they ultimately want the best for me. Was my mother right in telling the relative about me 'skin bleaching'? I am even 21 by the way.
