I am pretty much about to lose it!

I am so tired and cranky and really feel like admitting myself into the nearest Mental Hospital!

What is wrong with my DD2 (18mths)? for about the past month now she has been soooo majorly clingly to me! will not go to anyone else, always wants mum mum mum mum! I am fine with that, makes me feel loved and wanted.

But

I am over the constant whinging and whining. It goes on and on and on pretty much all day, she wants to be picked up by me all the time. Most of the time i am happy to pick her up for a cuddle, i know they are only little for a short amount of time, but when the pick up and cuddle dosen't stop the whinging that's when it starts to get to me!

I have not had a break at all from it, along with everything else i am trying to do, study for exams included i am exhausted mentally and physically. Tonight i lost it and yelled "for gods sake shut the f**k up" then i had to walk away. Now that within it's self is not me! i don't swear (well not in front of my girls) and im pretty calm cool and collect! I feel like the worst mum in the world for losing it tonight, but i have had enough!

I know she has been teething and that has given her grief, last few days she has had explosive diarrohea, and i took her to the doctor yesterday and she has an ear infection so is on antibiotics.

But whats the go with this all lasting at least a month? is it a stage she is going through? or is something else wrong?

I do not remember this at all with DD1.

I really am getting down in the dumps about all of this.
