求大神帮我用英语灵活翻译一下向外国朋友深表歉意的一段话。(从各种翻译机器复制粘贴的不要，太死板了)

would you please allow me to apologise to you!i really regard you as my close friend that i would not like to lose.anyway,please pardon my mistake,and i would be very much appreciate it.

Dear friend,
First of all, please accept my genuine apology. I'm very sorry for what I have done. Although I understand that not all apologies and wrong deeds can be forgiven, I still hope that you can forgive me. I genuinely see you as my great friend, and I cannot afford to lose you. Thus, please forgive what I have done. I will be eternally grateful, and I promise that I will never ever make the same mistakes again!

Sincerely,
Xxx
