My mom includes me in her insecurities

I don't think she realizes it, but she always tears me down while she is being insecure. My older sister is drop dead gorgeous, like 10/10 model. I have been aware of this my entire life, how can you not be aware? I don't think I am ugly by an means, if anything I would say I am rather attractive but not anywhere near perfect as my sister is. So I have always compared myself to her my entire life, I try my best not to be jealous because I have great qualities too and it isn't the end of the world if my sister is gorgeous.

But my mom.. whenever she is around she is always making remarks about how jealous she is and how WE are so jealous. We were at the beach and she said "she's so perfect don't we just hate her?" And I said no, I do not.

At my sister's wedding last week she kept making remarks to me about how beautiful she is and we have so many reasons to be jealous. I have learned to ignore her, but then she said "we are going to look so awful in the photos aren't we? While she looks perfect." I said. "WE? Why are you including me in your negativity?" And walked away. Does she not realize by her mentioning how beautiful my sister is and how we didn't get lucky like her, she is indirectly insulting me. I know my sister is drop dead gorgeous, but man I don't need constant reminders!
