Honestly, there are a myriad of ways to try to deal with this but I think for many of the things listed, I think you should probably stop caring so much. Having full on anxiety about drawing a paycheck but feeling you don't deserve it or something, just relax and think about yourself more than the morality of this. As far as bad code and needing to do a rewrite and your company not wanting to let you, at some point, if it is not your company, either look for a new position or stop caring about it so much, getting upset about it won't do you any good and if the executives in the company don't care that the code bad, maybe you shouldn't either.
