Stand in the place where you are
I think it is important for every person, regardless of what is happening to them, to be fully aware of the limitations the current situation places on them, and what limits are conscious, deliberate choices. I will admit, that when I was going through a very rough patch myself, some of what I was contending with was, in fact, necessitated by the situation. I had to move out of my house, and sell a lot of my stuff, because my house was foreclosing, and I had to contract 1600 sqare feet worth of possessions to fit into a studio apartment. I had to cram my 5 pets into a space that they did not treat well. I had to scrape together pocket change, and raid sofa cushions to put gas in my car, which was falling apart, and on the way to being repossessed. I had to accept underemployment, and disrespect from my employer, because $8 an hour was better than being homeless and starving. And I have, and will continue, to apologize to everyone who I imposed my problems on while I was indisposed.
Fact of it is, it took no small amount of time to divide what I could change in that situation, and what I couldn't. I could choose to be happy, and enjoy my friends. I could choose to share what limited meals I was able to put together with my pocket change, and share them with my friends, and I knew I could sometimes count on my friends to do the same. Even my friend who had just gotten out of jail, was on probation, and living in a week to week rental establishment that I can only describe as a whore-tel. When he offered me the limited hospitality of his room, he offered what meager things he had to share, and I did the same for him. He certainly did apologize for the limitations of where he was, but still offered hospitality, and got himself out of that situation as soon as he could.
When you are down, you owe it to the people who care about you to look into ways to stand up. Even if you are swimming in a pile of filth, people who care about you want you to see the options available to extract yourself from those limitations. When my car was repossessed, I really couldn't afford to live in Atlanta, since I had no job, and couldn't afford to move near a MARTA line, or even pay for MARTA. So, I cashed in a favor with some of divaalmaviva's family and friends, and decided it was better to be couch surfing and working in Upstate New York, with access to loaned cars and CDTA, than Atlanta, where the logistics of Atlanta traffic meant that I couldn't impose on my friends for rides everywhere. Even then, when I came to Upstate New York, I accepted the offer of help that was extended to me, but while I did so, I contended with moving divaalmaviva and I beyond the point of needing such assistance. When we had enough, we got a car on the road. When we couldn't eat alone, we shared meals, but made sure that there was enough to share, even if it was stone soup. I pruned so much out of my life through that period, though. Plus, I learned that the only thing that cannot be taken away is your ability to make something from nothing.
If someone can't see anything but the filth, then they need to get whatever help, whether from friends or professionals in mental health, that will enable them to carve a path out of those limits. Even when I was at the bottom of a hole, I stood up, took what hands were offered, and made sure that when someone offered me a hand, I thanked them and made sure that I could do something for them. If I couldn't, I would have felt bad for accepting that hand, and apologized.
With the economy the way it is, it is not reasonable for people to go it alone. Even if someone wants to ensure that what they have is the fruit of labor done on hard, frozen, unyeilding clay, such labor is only productive when there are farmhands there to help, or draft animals to pull the plow.
