Trev,
I am hoping it will help you to hear this. A lot of what you are doing is expressing how you feel, and that is VERY important (not to mention very brave).
As an abused teen you have a lot of extreme feelings: about yourself, about other people, and about what happened. All that stuff is mixed up in a very confused way in your head, and that doesn't make it any easier to talk about it.
It's rather like having a jar of coins: lots of different kinds and all mixed up. If you want to make any sense of the jar, you have to count the coins. But you can't take the quarters out first, then the dimes, and so on. They're all mixed up together. So the only thing to do is dump out the jar, then start working with what's on the table. It may seem a chaotic way to do it, but what other way is there? Anyone with a jar of coins would have to do the same thing.
What you are doing now is dumping out the "jar" of YOUR feelings, exactly as all of us have done in the past or in some cases are still doing now. You aren't doing something weird or bad. You are doing exactly what you HAVE to do.
No one will be angry because it's your mess on the table. It's your turn! Everyone knows and accepts that. As you sort through what's on the table we will all try to help you to "count" and see what's there.
I could go crazy with this comparison to the jar of coins, but it's the weekend so I will spare you.

The point is, bro, just say what you need to say and don't worry about apologies. You are doing exactly what everyone else is doing, except in your own special way. Everyone here expects that, and we all respect your right to do that.
So just post away Trev, and we will be here for you.
Except, of course, hands off the Joe Cool glasses please.
Much love,
Larry
