お返事がないので、たいへん心配しております。
スペインの経済状況が良くないと、新聞やニュースで聞きますし、あなたはいつも返信をすぐにくれていましたから、心配しています。もし、私で力に慣れそうなことがありましたら、率直にお申し出ください。
私は、あなたから最初にもらったメールに返信がすぐに書けず、失礼をしたことを今でも、恥ずかしく思っています。
I have heard that the economic situation in Spain is not well on news and newspapers, and you always replied me immediately so I worry.
If there's anything I can help you with, please don't hesitate to tell me.
I still regret that I couldn't get back to you immediately after you sent me the first email.
Because the economic conditions in Spain isn't good according to papers and news, and you always used to give me response quickly, I'm worrying. Please be free to ask me immediately when there is anything I can do to help you.
I am ashamed even now for having been rude not to have replied to the first email I received from you.
