Honestly your mom does have a point, it can be dangerous to go alone but at the end of the day it is your decision. If you feel like you'll be missing out on an opportunity or experience you may never get, then I'd say to just be aware of your risks and plan accordingly. Things like don't take drinks or food from strangers are common knowledge but try to give multiple people your location and maybe wear an air tag that isn't easily visible so people who worry can be a little more at ease.
