At some point, you’ll need to decide if you’re going to be a direct helper, or enlist someone else. If you do get involved, will it be ongoing or just in the immediate future? Are you skilled in the right areas? Do you have the time to make this kind of commitment, or do you already have life overflow yourself? Are you emotionally resilient enough or would a professional be a better fit? It’s important that you ascertain within yourself what feels right, and then communicate this as clearly and gently as you can.
If you can’t take everything on, there may still be some genuinely caring ways you can be supportive. You could offer to do some research and then provide them with some articles, or find a counsellor who specialises in a space that’s relevant to the situation. You could even offer to attend a GP appointment with the person who needs help, if appropriate.
If it’s a workplace situation, you could offer to get the person home or to a safe space, or suggest sitting in with them and a manager as a neutral party. In a family or work structure there can be clear chains of command that need to be respected, so don’t step in if you feel uncomfortable. Instead, explore the environment specific options that are available, such as employee assistance programs, the HR department, student services or a counsellor.
