Friend says I'm an Aspergers

Sometimes I have no friends at all, now and then I will make a friend or two. Lately, I have only one friend, we spend every weekend together almost. She thinks I have Asperger's syndrome after meeting someone at her Bi-Polar support group who had it.
I go to therapy for depression, and told my therapist. My therapist doesn't think I have it.
I do have an autistic sister, my dad exhibits some autistic traits but I don't think he is.
Could it be that you could just have some autistic traits if it runs in your family without being an asperger's or autistic?
It would be an answer to my life of social ineptness. I am a girl and they say it's harder to recognize in girls.
I guess it would be nice to have a label for my social ineptness, so when people tell me to smile, open up, talk more. I could say I have something serious like Asperger's and they would leave me alone.
Maybe I don't, maybe it's simple and I'm just a introvert with poor social skills.
I don't really consider myself "shy" but other people are always telling me I am and it's something they want to you to fix, like being fat, everyone wants you to fix the "problem" and lets you know. Tweet
