Translation of befürchten

Grammar exercises give the teachers and the students different ideas. We discussed the need for exercises in my previous email, but unfortunately I did not receive any further feedback since then.
Somehow, my email was not sent. There were even a few mistakes, but really only minor things, nothing really bad. I've already read some other texts that you have sent and are getting better each time.
I hope there were not too many mistakes here. I have learned Spanish not a long time ago and I am still very insecure! Tell me please, where do you come from and what you do?
