So like… I feel scared about the idea of like… just going for a walk all by myself…

How about making a list of the things you think would possibly happen to you going for a walk by yourself that would justify being rationally scared. Then go through the list and consider even if each event is possibly, how probable is it? I think you’ll find that that things you’re most afraid of are the least likely to happen.

Now as a comparison, make a list of all the things that could happen to you staying at home. Another list of all the things that could happen to you being driven to your destination. Assign realistic probabilities to each event. I’m guessing you’ll find that the probabilities of bad things on each of these three list will all look pretty equal. If they are equal, then going for a walk is no more dangerous that staying home or being driven somewhere.

In a sense, if you’re afraid to go for a walk, you should be equally or more afraid of going for a drive or staying at home. As such, its not more dangerous to go for a walk than the other option.
