First of all welcome to the group.
Second Thank you for such a positive post.
I completely agree with what you wrote.
If you have not seen any of my posts I am a 25 year old with facial PWS. Like you I have excelled in school. I never really had any relationships in my life. Just one or two, but that does not matter anymore because I am engaged and my birthmark does not bother my fiancee what so ever.
One thing that helped me was turning PWS into education to children. Adults still can be mean, but the way I have always seen it, it is their problem not mine.
Thank you again for your post.
