Depression is interesting. I don't completely suffer from it. There are times I get depressed, but I usually allow myself to feel that way. I don't complain about it at all or seek to change it. In fact, I kind of enjoy it. I probably don't get as depressed as you are right now, but it's not a completely foreign feeling.

I wish I had some good advice for you, since you're obviously looking to sooth your symptoms with your post.

Do you know what is making you sad?

Otherwise, I find that connecting to myself by reviving old interests (intellectual interests and artistic) helps me retune.
