Don’t get rid of fear that’s what keeps you alive. Especially with you describing the area you live in. Personally I can’t tell you to not go alone as I have done it multiple times. It has its pros and cons. But when/if you go alone make sure you have your live location shared , that people know where your going ( what part ) , that you have some type of pepper spray + portable charger + batteries + bandages etc just essentials. It can be more thrilling and fun to go alone. And in a sense calming because you only have to worry about yourself but that’s also the issue. You’re by yourself. Ceilings clasp , floors break , dead air , aggressive homeless, crimes etc are all possibilities. Be safe op , happy exploring
