@Jibu... Doesn't offend me, and I've been homeless.
Especially because the reason I was homeless was exactly what the OP is talking about being envious over: not having to deal with all of the bullshit from modern living. Not being responsible for people. Not having people depend on me. Not needing to be for others what I was unable to even be for myself. I was completely unable, at the time, to do any of that.
Many people with PTSD get so bad off they have to have other people take care of them. Whether family, hospitalization, supported living situations... At least homeless, one is still able to take care of themselves. Not completely incompetent, yet. Been that, too.
Both levels of care are real aspects of PTSD that people go to. As do ideations of both levels of care. With the accompanying fears: of what happens if I can't take care of my family? What if I can't take care of myself? Flip sides to most coins. Not talking about it because it's offensive? Well, why not just scrub the whole site? Why talk about any aspect of PTSD? People can talk about wanting to die, and that's okay, but not talk about wanting to be homeless? Where is the sense in that?
