Am I overreacting??

So I woke up early this morning and I don't know why, but I instantly grabbed my phone and tried to unlock it and it randomly erased itself!! It completely reset itself to factory settings!! I finally got it to restore from my Google account and I have to add a few contacts that it erased randomly like my mothers, but it remembered all my stupid games and everything. It erased pictures, but I had most of them saved to my sd card luckily, but it didn't save my text messages. I know that it's just messages, but my very last conversation with my grandma before she passed away was on there. I read them often because I felt like I was still talking to her. I was and still am extremely upset that they are gone. I am very close to my husband so I called him balling because the messages were gone. He told me to get over it because it's just a conversation. That hurt so much coming from him. He of all people know how sentimental I am and how much my grandma meant to me! She was my best friend. He said I am being dramatic and a baby. I don't even want to talk or look at him now. Do you think I am being a dramatic baby??
