Little problem

<p>Hi all,
I’m facing a little problem and I’m not sure what to do. A while ago, I have accepted my scholarship at TexasTech University and sent them my financial documents. However, recently, I just founded out that I have some relatives and friends studying at University of Houston, which I also got admitted and given scholarship. I really want to withdraw my decision and accept UH’s offer, but I’m not sure what to write on my e-mail for TexasTech.
Please help! </p>
