BROKEN RELATIONSHIP

I had a relationship break up 2 and a half months ago, It was very sudden and very painful. I am finding it difficult to come to terms with. Nothing that I do helps, and I am sinking deeper and deeper into depression that I cannot get out of. Like being in a well, climbing to the top--then falling back again, each time even deeper than before. What will happen when I cannot fall any further. I cry all the time. I have no family around, so I could cry all day, noone would care. My friends do not understand. I am ashamed of myself as I know that there are so many others worse off than me, but nothing helps. I am due to have a telephone assessment with a counsellor tomorrow. Has anyone else had this, and does it work ? II have other issues from my past that are haunting me now too.
