Hi Alice:

It doesn't surprise me that you'd become more paranoid after starting a new job. That's stressful, and if you're anything like my son, stress increases the paranoia and psychosis. It's a good chance to work with it - recognizing triggers, managing stress, noticing how you react to stress. Don't let it freak you out or make you retreat too quickly. If you like the job, stick with it, but keep an eye on your anxiety and stress.

Btw, that lady is giving you bad advice and just trying to scare you into giving up. My guess is she'll show up whenever you're doing well. Don't let her get to you.
