>asking for a therapist
ONI would probably give us some shrink like Veronica Clayton, which would do way more harm than good...

Honestly, just let them all vent on Sven privately like they have been doing so far (Carris when she killed the trainer, Daisy's group, Soren, Shika, etc.). Lend an ear, implement changes if necessary since we're in a unique position to resolve their problems, and embody the self-overcoming Ubermensch ideal to inspire them forward instead of being a little bitch. Easy.
