Slow loading website

Hi there,
My blog, as far as I can tell, is extremely slow loading up. Would really appreciate some help.
I have been told that I have Google analytics loaded twice on my site and that this is causing issues. Apparently there is something where it is sharing and this is why it takes so long to load? I cannot find where I loaded the code on for this. I know I am hopeless.
If someone could point me in the right direction then that would be great. If there are any other problems with the site that can be remedied with the speed then that would be appreciated.
Thanks
Cole
