Desperate Rambalings !Need Help!

Crystaleyed

So like everyone else I had a really good feeling this time last year. I hadn't had the best year and I was determined that this was going to at least be better than the last. But in the last month things have really gone downhill. Although I am receiving Counciling for Binge Eating Disorder I have never been diagnosed and therefore my immediate family (Mum and Dad) don't believe it. I have also been slipping in and out of what, according to the NHS (National Health Service), is depression.
This has been going on for a good ... I dunno ten months, ever since the summer exam season really.
I have also just this month started having panic attacks, which is the most worrying, no one knows about that or the depression and there are only a very small number of people who know about my ED.
I'm really worried about it all, which is not what I need and I really need a way to snap out of it ... in three days I am going to a university audition and my fragile state of mind is really worrying me, not only in a general sense but also because of the audition.
I don't know what to do or how to get help
My dr never got me diagnosed with an ED and I doubt he would even if I asked, he certainly wouldn't with the other stuff and talking to friends and family is useless because a lot of them don't believe that I have done some of the things I'ce said I've done and besides, the fact that I have been let down and betrayed by three different people in the last ten month hasn't done much for my trust in people.
