Hello Plshelpme, and a warm welcome to you .
It's never easy talking to anybody or even posting a comment on a site when depression is concerned because we feel that no one is going to believe what we have to say, especially when they aren't suffering from it themselves.
It's difficult to know how to put what you're feeling into words and many times we get caught or get stuck on what the point is we're trying to make, so writing down the main points of how you have been feeling is a great way to begin the conversation.
It can break the feeling of unease, especially when you are asked to answer 'what's been happening', so you may have a tendency of freezing up.
Sit down where you can and just start writing your thoughts down and if you want someone to go with you then please ask them, they can sit in the waiting room while you talk to someone.
There is also a depression test K-10 which you can do several times, not straight one after the other, but different times and different days, then you can take this with you when you see the doctor, this will once again be a sign they will know how you are feeling.
I hope this will help you and I'm so sorry you have to suffer from this most insidious illness.
My thoughts are with you.
Geoff.
