You can learn to deal with a lot of your "problems" or what they lead to. For instance, if you have trouble speaking to an authority figure, you can learn to cope enough to get through an interview.
Mostly though, you can realize that your mother was correct. There is nothing "wrong" with you because of AS. Everything you may perceive as a weakness, also has a corresponding strength. You don't like to socialize in groups maybe, but you can deal with solitude better than most. Perhaps, you are too blunt, and take things too literally. But you are also honest, and direct when giving your opinion. You might get wrapped up in something so much that you loose track of other things in your life. On the other hand, you can fully explore a topic or activity until you have basically mastered it. Look at your "problems", and learn what is the positive side.
Learning to accept who you are, and having confidence in yourself, will allow you to work on specific issues more easily and constructively, instead of just beating yourself up.
