Online help?

I have noticed that there is a lack of UK online counsellors/psychologists who can help with a specific problem and answer really quickly. Have you found that? There are forums such as this one where someone can answer and be really helpful but getting advice online from an expert seems to be lacking. I know you can google specific questions, but to get answers from someone who knows just doesn’t seem to really exist. Like a proper agony aunt. I have noticed that there are a few counselling sites where you can receive CBT/counselling over a period of time but not an advisor on certain questions. I have really searched! If you know of someone, could you let me know please? It would be really helpful :)
