It can be a helpful experience
I’ve had some good experiences some bad very much depends on how much the person who answers listens to how you feel and what response they give. The call wait times do need improving 8/10 I’m waiting in a queue and can still be number 4 in the queue after waiting for an hour so most times end up hanging up and never managing to get through to anyone which isn’t helpful when you really need to speak to someone about distressing thoughts.
