I almost hate to do this. Our English language expert has done it again. Note that "yourself" is a reflexive pronoun, in this case, you should have used "you". Your second "sentence" is structural garbage. With a question mark, a comma and then a "because", it seems to be a very strange piece of writing from someone who claims to understand sentence structure. As I said, don't mock others when you can't do it yourself. (Note that "yourself" is used correctly here.) I hate bullies, but the thing is, a bully is always riddled with weaknesses, that is why they are the way they are.
