Please and thank-you in advance to anyone who can put this is turkish for me!

I am going crazy! Where are you? My sister and Paul came and again were here all night. I don't know why they do this.

Çıldırıyorum! Neredesin? Kızkardeşim (Ablam- if she is older than you) ve Paul geldiler ve yine bütün gece burada kaldılar. Bunu neden yaptıklarını bilmiyorum.

Ayla, I tried to translate this message as well... Could you please explain me why you wrote 'yaptıklarını'? This is the only part I wasn't able to do.

Thank-you so much! and very fast too. Oh, and yes she is my older sister.
Again thx a million!
