I was watching a TV program t'other day, where lots of otherwise homeless people, and deliberately homeless, had bought themselves a motorhome, to live in, and were wild camping for free around the UK. Some in wilder parts, some in their employer's car parks.
If your 'anxiety', is proper medical anxiety, and causing you problems, versus just the usual anxiety which life throws at us, then pester a doctor. If you have been reading my posts, I have suffered it, undiagnosed, and very debilitating for the past 12 months, and becoming a worsening issue, several times a day. Last week, it was diagnosed as anxiety, prescribed a med, and I am much, much better, I got my life back.
