Pic unrelated, Not mine mine but looks nice

Been made redundant and I can't afford my rent anymore so I chucked out a ton of applications and all companies near me aren't hiring. Banks about to run dry soon, got about £100 left so I gotta sleep rough for a while, or forever.

I'm not living in the city there's a forest around my town I'm gonna live in. Gonna get a 1 man tent, sleeping bag, take some pillows, solar USB charger. Only just come to terms with this news so yeah, I live in the southeast UK as far as climate is concerned, I still have access to my parents house occasionally, to fill up water and such so I not 100% dependent on nature.
Any other advice for sleeping rough?
