English is not my mother tongue so please be indulgent.
In my family, we are pretty close to each other. I mean, when I say "family", it includes aunts, uncles and cousins. With my big sister, we grew up with my cousins and one of our aunts. They were all born in the mid and late 1980s. And here I come, born in 1993.
As I am the youngest and the shiest, I was quite often left aside and couldn't build any relationship with them. Plus, I had and still have a rather difficult relationship with my sister.
When I was 20, the situation didn't change. They never shared anything with me. They never asked me to go out with them. It's not like they are much older than me. Even when they are talking, when I'm here, no one talks to me. I know I should try to fit in, but whenever I try to give my opinion, it's like I shouldn't, because "I don't know what I'm talking about." They don't even listen to what I have to say.
Even now, no one thinks I can think for myself and make my own decisions because everyone sees me as a child who is influenced by everything and everyone.
I have lived by myself and had a job for about two years. And most of them don't. I am not saying that having or not having a job justifies whether you are mature or not. I am just saying that even if I proved that I'm responsible, they do not see me as an adult.
My relationship with my mother is pretty much the same. She still sees me as her little baby and tries to make me do whatever she wants me to do.
She has a lot of personal problems. And whenever I try to help her, she doesn't consider my advice. But if her friend tells her the exact same thing I did, she thinks about it and says she’s right. It is rather frustrating.
I shouldn't care about what they think of me, but I have a pretty low self-esteem, and their rejection doesn't help. In family gatherings, I am always put aside. It has become distressing for me to see them.
How can I make them stop seeing me as a child?
Should I just ignore the situation, since I cannot make them change their behavior?
Edit 1 : I forgot to mention that we are a Turkish family who lives in France. My mother came here when she was 4.
Edit 2 : I don't know how to say this without sounding rude and arrogant but almost everyone in my family is narrow-minded and never question themselves. For instance, I have been a vegetarian for about two years and they still insult me, saying it's useless and that I am just following a trend. They don't listen to the reasons why I am a vegetarian and discredit me everytime we eat. I am not forcing them to do anything, or annoying them about it. But they keep coming at me. I know it's not the subject, but it was just an example of how intolerant they are.
Edit 3 : This topic is not just about my family members seeing me as a child. It is also about them rejecting me for not thinking like them and imposing their way of life on me.
