Wow. Depression and anxiety can be treated easily. Suggest your friend speak with a different doctor and ask to try some low dose anti-depression meds... (which also treats anxiety) I’ve seen people have a complete reversal of mood and feel better within a couple of weeks. Modern serotonin medication isn’t like the old school with lots of bad side effects. I’ve seen it work miracles. You can even see a doctor at a clinic for this, they will often give you a prescription.
