Wedrifid's comment still applies. Examine the social pressure, identify how it produces guilt in your mind, and then change your mind so that it doesn't produce guilt no more.

Recently I've really liked the "brain as cognitive engine" metaphor, so in that vein I offer you a different interpretation of what "change your mind" means: altering your brain. So changing your mind is no longer "I believed X, but now I believe Y" and is more like "My brain used to generate X but I shut off the Z input and removed the Q cogitator and now it generates Y".
