Translation of cheer up in German

I started to speak Spanish because i had i boyfriend from Mexico. Especially I've never learned Spanish . I only listened and repeated what he spoke. Now i speak Spanish well but i need to learn grammar rules.
I was very busy during the last month. I had to write some letters to find a new job. Thanks for your message yesterday evening! Where do you life in the USA? I have never been there, not yet, buy I will one day.
Sorry but I hadn't have enough time in the last two weeks to respond to your email and to your interesting offer. I really need to think about it a little longer, and I am sure you'd understand.
