I feel so glad that you chose to share your discouragement with Jes. She shared some good ideas. I know what its like not to be able to fix things up like you'd like to. Even after 28 years, most of what we own was either given to us (usually second hand) or bought second hand.
Please don't be discouraged. You've got to get creative. Find the things that cheer you. Maybe a candle burning (often cheap at yard sales), music playing (try Pandora or Spotify on-line if you don't have a collection), the fragrance of supper simmering on the stove shouldn't be underestimated!
I find that when I think about what I can do instead of what I cannot do, it helps.
When I didn't have furniture for my living room, I baked cinnamon rolls and sold them to businesses in town for their break times. I bought my furniture from Craig's List. Perhaps there's something you could do to make a few dollars here and there. I get to squirrel away all the money I make by selling books on-line to buy my school books and whatever I can use PayPal for.
As for hospitality, years ago we had people over even when we had to sit on the floor,
We once went for Sunday dinner to someone's house and they served a simple bean soup with cornbread. Inexpensive, true, but hospitality was given as they shared what they had with us, and we enjoyed our time very much. Their situation and home was similar to yours, but it was the friendship offered that I remembered.
If blogs and Pinterest discourage you, don't look at them! If you do look, just let them be jumping off points to think about what you can do with what you have available to you.
For now, think about the things you have that you do enjoy and how you might make the best of them.
Here are a couple of posts from my blog that might be encouraging to you:
