Whenever I bring it up ("Mom, I think I have asperger's...") she dismisses the idea as unimportant. When I talk about the things I struggle with, she always answers, "Oh, everyone struggles with that to some degree." I feel like I'm not being taken seriously, but I don't want to make a bigger deal out of it than I ought to. It's just... I would really like to know if I do in fact have asperger's, but my parents don't seem to care about finding out. What should I do?
Trust me, I know how you feel.
I was PROFESSIONALLY diagnosed with ADHD, BPD, OCD, SAD, and I'm self diagnosed with ASD. My family dismisses the whole idea of disorders even existing. They believe if you're not mentally retarded - you don't have any disorders, it's just a part of your personality.
I used to hate them for that, but with time I accepted their opinion in order to preserve our (already weak) relations.
I don't know much about your parents, but you may try convincing them that you really do have ASD. If you have enough money, go to psychologist. I'm 18 years old and I used to pay my own, after I was diagnosed my country paid psychologist instead of me. Research about your country's psychology support.
I usually keep my problems away from my family, but I don't suggest you to do the same. It will damage your inner peace.
You need to find a person who will listen to you and can relate to you, and the family is the best choice. In the end, family will always be there for you no matter what happens, even if they don't understand you.
