If you should go in a show like this, it must be with one of your parents.
I don't know your parent's version, so if I should give an advise solely based on your statement, I would recommend that you all go together in order to bond. Some kind of communication problems exist, and it takes two parties to solve it.
As a parent I can understand how stressful it is when the child is bullied and we as parents only observe the reaction not the cause of the problem. If we don't listen very carefully, we don't get the message. And it is difficult to listen due to all the interference from outside sources like phones, work, TV etc.
The wilderness sometime is the answer because the necessary peace is present. I mean sometime, because there are other ways to isolate you and your parents in a peaceful environment. Some kind of remote area must exist in UK.
However, you will all benefit from having a third license party present when you talk. We all have our version of the real world. Sometime our version is a bit coloured by our opinion. That can block the advance in the conversation. So a little help from a third party can make the push, you all could need in order to come to some kind of agreement.
I hope you did find my input helpful.
