friend, who are you? I don't think I know you. If I reject you it'll be mean, but I really don't know you. If you would introduce yourself - oh well, I'll add you since you'll probably introduce yourself later
Remarks about the translation
Something is missing from the first line - the word "disiyorum" is meaningless, but I'm guessing it means either "düşünüyorum" (I think) or "endişe ediyorum" (I suspect). In both cases, the translation as it is would be correct.
I think either reject or turn away would work in this case as this was an answer to an invite to be added as a friend on facebook.com. I am very satisfied with the translation I receieved as it answered my questions. Thanks you all are terrific. Kendine iyi bak!!
