Meeting a person you have only ever talked to online is a very risky thing.
You might think that you know them from your conversations but you can never really know who you are talking to online.
Now you should tell a responsible adult what has happened. You can tell you Mum, Dad or Guardian and should never feel embarrassed about the situation.
You can also contact the Police on 101 if you have any concerns or worries about an online conversation.
In an emergency ALWAYS dial 999.
