I'd been feeling so positive for sometime and now I seem to have come back down to earth with a horrendous bump.

I'm a negative person by nature so it's very difficult to be positive so I'd been rather smug about my cheerful moods. It seemed like such a big achievement but now I just feel despondent and disappointed with everything.

I'm not entirely sure why I feel like I do but it all started on Friday.

Molly started the morning off in a grump. After we'd taken her to school Charlie and I went into town to run a few errands but he was so badly behaved, the worst for a long time. He nearly had me in tears in M&S and I was getting so stressed. I cancelled plans to meet Nigel for lunch as I just wanted to get home.

Thankfully he calmed down by the time we got home and spent a little time next door with his cousins. He then fell asleep half an hour before going to collect Molly from school so waking him didn't make him a happy bunny. He screamed all the way to school and the whole time we were there. So embarrassing, no matter how much you know the other mothers have been through the same at some point. He cheered up once we got Molly but then she decided to play up all the way home. I wasn't going to win today!

Nigel was in London so I was alone with the children until late but they went next door with their dinner and I had a peaceful hour alone. It was bliss. When they came home the three of us got changed and all climbed into my bed and it was the most relaxed part of the day.

Yesterday wasn't so bad but the children's behaviour easily wound me up. Today they were mostly well behaved. We walked from Pakefield to Lowestoft and back again with Nigel's family and it was a lovely day but I just feel so low.

I wish I knew why, then I could deal with it. Other than Friday, I've been having some really good days and have been keeping busy. I love helping out at the school, which is twice a week at the moment, I have a couple of other things in the pipeline and I should feel as though I am actually doing something other than just being a mum and wife but it doesn't feel that way.

What is wrong with me???
