How to say this in a better way?

I watched a few videos and read hella lot of articles and started to replace the screen. But my sister kept scaring me saying that i will definitely break the glass as i have never done anything like this before. Due to all the complaining i decided to stop the repairing process after removing the broken glass and seek professional help by contacting a local shop. They did the job well without even charging a fee. The iPhone works fine now.

After reading many do-it-yourself articles and watching several videos on the subject, I started to replace the screen. My sister, however, scared me by saying I would break the glass. Because of her warning, I sought professional help at a local shop. They did the repair easily and correctly and didn't charge me. Now my iPhone works fine again.
