I agree regarding the books. I've felt the same way. But for me I think because I didn't apply the techniques. Not just for depression, but for social anxiety and other skills.

I understand your feeling, but as I understand it a social support is a group of people you already know, and who can give you support in your crisis times. I am not sure if you can create such support while at your worst. I think keeping this in mind when you feel better is a good idea, for next time you feel down. For now I think you need more of an immediate mood lift. You told me things I wish I could do, like volunteering, and interacting with horses. I like in particular the lesson from the horses, that you need to take the first step to own them. So, I am using your own stories to encourage you to take the first step, again. I believe the start is the hardest part. You just need to get over your own thoughts, or rather to do something despite them.
