Ok, I hate admitting this, but I have chronic PTSD and I have been able to skate through every psych eval thrown my way. It's because they're looking for signs that you're DANGEROUS or so unstable that you can't be trusted with some function of the job. You will be asked questions about whether you hear voices, believe strange things, have hallucinations, and have ever harmed people or animals. They will ask questions to gauge if you can't physically sit still, if you have racing thoughts, or if people have expressed concerns about your behavior to you (gauging for bipolar). They will also ask questions about how close or connected you feel to people, if you think lying and stealing might be justified, or if you ever have violent fantasies (gauging avoidant or borderline personality disorder).

At the very most, your test will come back to show that you're introverted and have an active imagination (I'm just guessing). Those just aren't things a psychologist will pick up on. You don't have to tell them about medication you're on. They cannot discriminate against you on the basis of you having depression or being on prescription medication. They honestly probably won't care all too much if it does slip.

You will be ok. feel free to message me if you have any questions aout psych evals. I have taken a bunch of them and I've even scored them for other people as part of previous jobs I've had.
