Prayer is simply just talking to God. Get on your knees (or what I like to do, sit on the floor in my closet with the door closed) and conversate with Him just like a regular person. Of course the devil will try to make you feel like it's silly and awkward, but God appreciates it, and He understands. We all have to start somewhere, and that's giving Him something to work with, rather than not praying at all because you feel you aren't good at it.
