Geçmiş olsun ben uyudum o yüzden yazamadım. Dün senin için internete gittim . Sen çıktın ama

My attempt:

(I hope you) get well soon. I slept that´s why I wasn´t able to write. Yesterday I went on the internet for you, but you left.

Get well soon, I slept, thats why I couldn´t write. Yesterday I went to internet for you (it may be "girdim", instead of "gittim". In this case: I loged in internet for you). But you exited (from internet).

thanks for all
