First of all for anyone who has battled depression your choice of words have nailed it, and they will get it. The fact that it does not seem labored or forced speaks well to your skill also. If I might just make a suggestion or two 1. since you are rhyming your away/stays is a little off for the flow. 2. Unless you are on purpose attempting to make a connection to the Great Depression I would drop the capitals, I think it draws away from your message other than than Good Job I really enjoyed.
I see, you are great rhymer. That was well done. As far as the content. I think and I think and I think that I think, but I think that I'm not thinking when I'm actually thinking that I think. How else could I think when I think not that I think? would I then be thinking? Or would I not be thinking that I think? That's the problem with my thinking, I think that I don't think when I think, but in reality I think and I think and I think about what I think until I start feeling that I do not think. It's pretty sad. As I think, I do not think, I think.
Anyhow, reality is starting to feel better day by day. I'm thinking a lot less. It's less exhausting. I can relate to your poem in the thinking. It was well written. But as any other poems, I think there's always room for improvement.
