You were a page from the past, you were paled

Nowadays, you will scare most from the people who you did favors.

Greatness is that you do not compliment anyone, you do not cheat anyone. Which real ideal is good for country, you will see it and walk to that goal. Everybody will be against you, they will try to divert you from this way. At this point you will resist. Endless obstacles will be put up in front of you. You will overcome these obstacles by considering yourself not great but small, having no means, nothing, believing that there will be no help from anyone. And then, when they tell you that you are great, you will laugh at them.

May God damn me and I´ll get out of it

Yes, you are right. That way, your translation is better.

Sevgiyle, anne, baba ve küçük kardeş Ken.

Güzel prensesimiz Sarah´ın doğum günü kutlu olsun(doğum gününü kutlarım). Harika bir gün geçirmenizi dilerim. Anneye, babaya ve küçük kardeş Ken´e sevgiler.

Hello my flower,

How are you today? I hope you are fine and peaceful.
I went to Istanbul-Topkapı Central Post Office for the package you´ve sent..
The packages which cost more than 75 euros are stuck in customs according to Turkish laws. The package will be returned to the customer after 20% tax fee would be calculated and paid. I have paid to the post office and got the package.
I am writing to you because you were so worried about it.
You were realy made me affected. My feeling about you is developing everyday  when you show sincere behaviors to me. Loving is a good thing, but to be loved is so special. You are the best person in my life who has a strong character, a pure heart, who is honest, merciful, smart, mature, emotional, proud and kind... I am very happy and lucky to find you.
I thank you forever for the presents you´ve sent to me. My eyes are full with tears for the value you give me. Emin and Beyza also thanked you. Especially Beyza loved her present
Many people came and went in my life, they were forgotten in time. But for me you are so different than those people. I will never forget you. Do not have doubt about it. You are so precious and valuable for me. I do not want to lose you ever.
I love you so much... and I miss you a lot... I miss your smell... I miss your smile... I miss your hug... I miss your cooking... I miss sleeping together... I miss kissing you... I miss touching you... I miss feeling you... I miss hearing your voice... I even miss your coffee drinking without having a breakfast I miss everything about you...
I am waiting you here with patience.
Take care yourself and be careful. Do not be ill, do not get yourself down and always do try to be smiling. You deserve the best and and the most special of everything. Because you are a wonderful person...
Goodbye,
Kisses.

As Henry said, they might have been talking crap but it might also be real.

I think he did not mean bloodthirstly, but something else. Maybe used a wrong word or meant something else. Looks like he tried to mean he would travel a lot, he would go many places.

"Sleeping with Spanish women" I think there is the meaning of having intercourse in this sentence. Otherwise, why would someone write a sentence like that?
