I am loved by both of my parents but I always have a feeling that I don't belong somehow. When I was around 3-5 years old, I rememebered my 2 sisters, teasing and bullying me. I remembered the words they said : that I was picked from the road because my mom pitied me. Now that they are older however, they have almost never teased me anymore, more of ignoring. I've seen my birth certificate/record (not sure) but I saw somewhere that this could be faked ? Is it true ? Im the youngest of my siblings and am really curios whether they were jealous of all the attention that my parents were giving me or was I adopted?

Siblings often say terrible things to each other.

I would take the "teasing and bullying" as just that - teasing and bullying. Ask your parents and if they say you aren't adopted, believe them.

And, yes, your siblings could be jealous. Ask them, too.

Well of course anything can be "faked" look at all the illegals with birth certificates, green cards and more all fake.

But if you want, order a new birth certificate from the state, but give you a hint, they don't say "adopted" it will list your mom and dad as the birth parents and there is no way to tell a birth certificate that was admended at adoption from one written at birth.

I am adopted, and I adopted one of my children, my birth certificate shows my adopted parents as the birth parents, just like my sons certificate shows me as the father ( although I am not the bio father)
