thanks for corrections hallederiz,
"Hepsi yalan mıydı?"yı iki kere yazmışsın

I'll try, but I'm not an expert in translating to Turkish:

Sana güvendim, sana inandım. Başkalarından farklı olduğunu sandım, fakat değilsin. Ãœzgün olduğunu bile demedin.
Ne zaman bu kararı verdiğini bilmek isterdim. Sanırım bu yaz olmuştur, fakat istediğini edinmemen takdirde beni o zaman üzmeye korktun. Nasıl sen ve arkadaşların benim aptallığıma gülmüşsünüzdür. Hepsi yalan mıydı?

(name missing here or "someone") has gone mad, some of them became corrupted

yes, you're right

one day we will watch both the sun rise and the sun set together...
you're ok with the rest

you are the only one in this heart

PART 47

The third person at the table was a young man named Oktay. He was a lecturer in the Tourism and Journalism Institution of Higher Education. Recently, in addition to teaching, he was carrying on with his doctorate studies. He was of middle height and rather overweight. Only his pleasant and continuously smiling looking face created an invisible likeable halo around him and attracted especially the attention of young girls to him. Oktay was a clean and an elegant dresser, a polite young man. He would speak little and wouldn't talk if not asked. I liked him especially for this reason. Almost every night, when I got out to eat, we would often meet at café's and sit together. Because he didn't drive me crazy with unnecessary talk, I preferred to sit with him. When I sat at the table, the first one to speak as usual was Serkan. He saw himself as the group leader and certainly to speak first was his own right (!?). As if he hasn't noticed that I had drew far from him, he asked, putting on an intimate expression:
- Ooo, my teacher! Welcome! What's up? We have already eaten our meal... we were just about to get up."
