You may be very concerned about someone’s wellbeing and would like to see them have counselling. But it really is best if the person in question can reach out for support themselves. I am able to take enquiries from you on behalf of someone else, but you should have their full consent and they must be willing and motivated to engage with therapy.
If you really feel you must suggest counselling to someone, do it in as calm and private a moment as possible. It’s important you express your concerns in a judgement-free manner. Make it clear you support him or her and merely want to see them be helped in feeling better. Then leave them to make the decision for themselves. Counselling is rarely effective when somebody feels forced to attend against their will.
