I've always been super-sensitive to others as well. It's one part of the reason I now live an almost exclusively reclusive lifestyle. You wrote you doubt you'll ever get over this state of mind. I think you probably can, although I would have to admit I never did... not entirely.

As I look back over my life, I can see where there were times that were better & other times that were more difficult. But the sensitivity was always there. I would hasten to add though that I never made any real effort to address my own problems in this area either. (When I was young, there was no help for this sort of thing.) I think you can follow a different path though.

Here are links to some articles, from PsychCentral's archives, on the subject of things you can do to cope with social anxiety, as well as on the subject of the highly sensitive person which you may well be:
