Walking outside is free! There are free support groups online. Those require time, but just 20 minutes can make a bigger difference.
The CBT workbook I used was maybe $20, I think. It’s worth the investment.
Finally, getting over depression is all about retraining how you think. It’s going to take time, practice, and effort. Depression wants to show you how you don’t have the resources to beat it. That’s not true. You can beat it, even if you don’t have the resources other people might.
Depression has forever changed me. It’s easy to think that it was for the worst, but I’m more empathetic to people than I was before. Something that helped me was realizing and believing that depression is temporary. You won’t always be like this, even though you might feel that way.
You can do this.
