Is this a city where it's safe and practical to commute to work on foot?

I'm in my 20's. I'm trying to escape an abusive home where I'm stuck with no car and only a driver's permit. In the state I live in there is no way for me to reach a nearby city to get a job on foot legally and safely and even if I moved into a homeless shelter in one of the nearby cities, there are basically no job opportunities unless you have prior experience in a similar role or can drive.

I have about $1,200 I've managed to save up from over the years. I was thinking about taking a Greyhound bus to Traverse City, getting a job at the Amazon that's hiring (which I believe is guaranteed employment pretty much, no interview process or anything) and working there for the weekend and trying to get a full time job somewhere else on the days that I don't work at Amazon. So then that's 7 days a week of working in the day and then i'd try to find a homeless shelter to sleep in at night. I have no credit score and no way to get a credit score until after I become employed (Because the chances of being approved while unemployed are very low and being denied hurts your credit score). I've thought about even trying to find a roommate in the city but I think I would have to act on the Amazon job before then because they tend to fill up very fast. I'm probably going to have to leave in a few days in order for this to work out.

So all of this is why I'm asking. I'm mostly just asking about the commute aspect of all of this (walking to work, walking to the bank, walking to the post office, etc.) but if there's something else you think wouldn't work about my idea, please let me know.
