Is my previous teacher annoyed with me?

It's not that he doesn't care, you just have to remember that you shouldn't get too involved with teachers outside of class. They have their own lives and work to do, while I'm sure he does care about your situation he doesn't need to hear a play-by-play. This is too much for someone who is supposed to be in your life only academically. Don't email too often, remember he's your teacher not your friend - even if you aren't in his class anymore.
