Frustrated with :( Diabetes testing

Lizbeth
So I just got the first touch ultra mini to test my blood glucose levels and I tried to start today, let's just say I wasted three of the test strips and it won't give me a reading , I keep getting a error code....called my doctors office and they said that they would call back before 5 ....I finally started to cry from frustration . I felt like a bad mother for not being able to do something so simple to be healthy
