Hey (insert your friend's name here) I wanted to tell you that we haven't talked for awhile from that day when I visited you. I just wanted to know how you felt this week because you got sick lately. I hope you'll be better because I was trying to call you for a lot of times and you didn't answer at all, I was just very worried about that your problem could get worse. I hope you will send an email back to see if you are okay.
-with love (insert your name here)
