Hey /out/, couldn't find a homeless thread in the catalog, so fuck it, I'm making one.

I'm going absolutely nowhere in life and I feel like being homeless can help put some perspective on things. I'm almost a complete hikikomori and it's going to stay that way unless I do something about it. I really don't see any other options to whoop my ass into shape.

I really have no idea what to do and was wondering what kind of advice you guys could give me.
Some supplies I recently purchased are a hiking backpack, a large blanket, a reusable water bottle, a handheld radio tuner, and a mini maglight. I already own a good pair of boots, jeans, and a light jacket.
My plan so far is to sleep in different neighborhood parks each night, buy cheap food from dollarstores/wal-mart, and drink out of water fountains + fill up my water bottle while I'm there. I live in Arizona, there's no snow and I wouldn't be able to handle a climate with it, so I'm not going to move around too much. I'd imagine it'd be a good idea to have some sort of weapon for protection, but what would be effective/concealable and be fine with police if I get searched for whatever reason?
