I, also, have felt the "sting" of having people say the same thing - "ask Laura, she knows all the answers". It isn't nice, but I think there may just be a little jealousy involved there.
The only thing that differentiates me from some of the younger students, in my opinion, is that I am, too, paying for my own education, so I need to make the most of it. I am way too old for Mom and Dad to pay, I have my own family, and would never qualify for financial aid. Kinda stuck in the middle ground, you may say. I'm no better, or worse, than the others...just different.
I also have heard that the older, returning students tend to do a little better, maybe because we don't have the time to do it all over again!
I guess the only thing I can do is remember why I'm in nursing school, and be true to myself. I have my family's and God's support, so I believe that is all I need to see me through!
