What do you do as a job? Do you have any career ambitions? What films do you like?
I ask you the first two questions to get a view on what else you may wish to contribute to the world. Is there a field you are particularly passionate about? The last question is to try and understand your likes and dislikes.
Also about mental illness... some of the most renowned scientists/ artists/ writers in history have suffered from mental illness. And yet, despite your view that they are inferior in some way, they have acheived/ contributed more than most of us ever will.
In fact, a recent scientific book linked creativity with mental illness.
Overall I would suggest you try and see people as people, not as some label of "ugly" or "mentally ill". People, in general, connect and form friendships based on a shared sense of humanity, that overides any superficial differences.
