I just can't relate

I just can't relate to people who say that they have autism, but have a job, a partner or friends. I have problems in every aspect of life and even basic things like shopping or making an appointment with a doctor are problematic for me. I'm also not above average intelligent or gifted in any particular area. Literally anything that requires mastering some manual or mental skill is difficult for me to understand and learn. I won't even mention problems related to relationships with other people here.
