You need a solicitor urgently , I presume you are charged with a section 18 wounding / GBH with intent. This is a very serious offence and if the charge is proceeded with and you are found guilty it is a compusory prison sentence.
From reading your story ( very difficult with out punctuation) you did have a bottle in your hand and the bottle did hit the other person and cut him. This is going to be a difficult one to prove one way or the other but you are potentially in a lot of trouble, get a solicitor NOW and tell him/her the story .
I would add that we see a lot of this type of story on here and the questioner nearly always claims it was 'self defence' .
