I feel terrible

My 8 month old is very active, pulling up, cruising along things, and manages to fall on the floor right in front of me! I feel terrible, here I am looking at her and I fail to catch her in time. I am so worried about the falling on her head everytime. I don't know if her crying is because of pain or shock. I once let something fall while cleaning and she was playing on the ground at got terrified of the sudden noise and cried a lot, same cry just like when she falls. There are good days when it almost doesn't happen but since yesterday she fell like 5/6 time by now. Anyone going through the same?
