Hi sorry to hear you are struggling, there are a few places to get support in the Uk.
Childline: offers support to children in the Uk not just with abuse or bullying but anything that’s bothering you up to the age of 18
The Mix: If your a bit older or prefer a more mature group the mix offers advice to people aged 13-25 on anything thats bothering you. They also offer a 1-2-1 support chat as well as group chats on Sun-Thursday.
The Samaritans: A call centre whom you call call and just talk to a councillor who can help you with anything thats on your mind.
Shout: these are like the Samaritans but they use a text service instead
I’m not sure if I’ll be aloud to post the links or not (I’ll check with a mod) but I could pm you the links if you like?
hope you’re ok
