I think it depends on the person. Different things help different people.
I had a private one suggested, back in the days when I could afford it. She did CBT and was absolutely fantastic and if I had the money I'd have carried on going.
They may be able to help with like coping techniques or just giving you an outlet to be able to talk about it, especially as it can be hard to speak to others about things without sounding like you are moaning and maybe give you some validation it's ok to feel certain things but also find ways to help you cope.
