Exchanging contracts or swearwords?

OK, its been a bit of an emotional rollercoaster.

I came into work fully expecting that I would exchange contracts today.

At 11.00 I received a call from the estate agents to say there was a change and they had decided to tie in this purchase with the sale of another flat. Bearing in mind this had never been mentioned previously and I had chosen them because they were not in a chain, I was surprised to say the least. After swearing at the estate agent for about fifteen minutes and havigna bit of a cry in the toilets I carried on at work. I would like to say "I carried on bravely" but given the way my colleagues were avoiding me I suspect " carried on like a psycho on day release" would be closer to the truth.

At 15.00 I received another call from the estate agent. Apparently the buyers solictor has just request contract release from my solicitor. This apparently means we are going to exchange after all. Apparently we are still on for completion in a week.

Having spoken to my solicitor they have not heard a thing so still no closer, or maybe we are, or maybe we're not... Heaven only knows. I am a bit of a wreck and desperately in ned of a lie down in a dark room.
