I feel the exact same way.
I've cut off many old friends because I didn't like the feeling that they were judging me -- making me feel like I was supposed to have accomplished more.
But I've had some friends who actually did judge me like this. A guy I used to "love" pretty much belittled me because I don't party or club. Another so-called friend said that I hadn't gone anywhere or done anything because I went to college in our hometown and didn't go away for school (I stayed because of my family, mostly).
The great part is realizing so many people are like us -- we accomplish stuff by simply doing something that goes against our SAD. Or we write or read. We have our own life landmarks. Heck, just managing a conversation with one person is an accomplishment for me. Just making it through work without a panic attack is an accomplishment.
Really, what do people expect us to have accomplished since they saw us last? Life doesn't have to follow the same path of dating, marriage, children, good job, etc.
