Hello, wow I can relate to your daughter a ton. Okay I just got diagnosed a few months ago with type 1 and I am thirteen as well. I am on lantus and the Novolog pen. I know when I first started lantus I got very anxious and before I had to take it, just in a dead panic. I can not fully answer your question, but I need your help. Can you ask your daughter if her lantus burns, itches, and/or does the area she injects it (arm, leg, stomach) feel heavy or like a big knot is under it?
