Hello Katie, and welcome!
You will find many friends here to help you. What you need to do is to start out with your basics, these are - meditation, visualization, and centering for now.
Please don't start doing actual spells before you've learned these first. They are the basis for all that follows.
There is also a "Newbies" section on this site, which will help you out a little further. Just go to the home page, and click on "Newbie Central".
