Don't feel too guilty about it, it's okay to make mistakes, sometimes. If you never drop things, can you please give us some tips on how to not? Are you more aware of what you are doing? Sometimes I feel like I'm a robot and do actions without much thought.
I dropped my laptop while it was on the edge of my sofa and my phone in the same week. This is probably the first time I ever dropped them since I got them. Sometimes I drop spoons or forks off my plate too or my PS4 controller.
