Default Need stock ROM for HTC Desire 300/Zara Mini. Please Help :((

Hello all, I am really desperate.

I installed CWM and rooted my HTC desire.
I was having a look around CWM settings to try and do a factory reset, but instead deleted the stock ROM from my phone.
It's a UK based phone.
I can't believe how stupid I am.
I can easily re install the rom via a micro SD card but it seems impossible to get ahold of the stock rom. Even HTC themselves didn't have it on their list. (which is annoying!)

Please can someone help me, I know it's not the best phone in the world but I'm travelling in the coming week and I need to be able to contact my family. Does anyone have any rom I could use so the stupid thing turns on!
