Thanks in advance for the help:

I am sorry I have not written or called in awhile, I was away from home for the last week.  I have not and could never forget you.  You are always the only thought on my mind.   

 çok üzgünum,sana yazmadým yoksa aramadým bir süre,evden uzaktayým geçen haftasonuda,ben seni asla unutamam,sen daima düþüncelerimde ve aklimdasin

"yoksa" is for questions indeed, not for negative "or" :S
