It is not that I am afraid of being in silence, it can be quite enjoyable. I find that music is a good way to keep me more aware of the passage of time. I tend to use it in my morning to have an idea of how much time has passed, otherwise I get too lost in my own thoughts or getting distracted doing little things and then having to run so I don't lose my bus. Hahaha.
If I am outside on my own, I must have my earbuds with me, if only to keep certain noises quieter. If I have my earbuds in, might as well listen to something nice, . I have a lot of playlists in my Spotify so I can have something no matter of my mood and what I feel like listening.
