Gray Cllouds

I am wanting to create another blog that deals with depression. I want to be able to paint a picture of what it actually is to help people better understand whatgoes through someone's head whose dealing with depression.
Last night I had what I call call a "bad night", nothing bad happend to me and it was a good day at work, but I felt as if my contribution to it was worthless. Nothing happend to made me feel worthless, i had a great day at work but I still wanted to cry and still felt worthless.
I also wanted to cry and when I was faced with trying to do more than one thing at a time I wanted to scream and flip out, but I didn't. I was writing an e-mail and then the phone rang and it was for me, Someone (my Dad) was waiting to use the internet so I had to hurry so I was writing my email and talking to my sister on the phone and then had my Mom telling me that I had to get my bills paid as my dad was waiting over my shoulder for me to free up the internet! This almost brought me to tears and soon after I finishes all tasks I ran up to retire to my bed. I had done it. I forced myself to complete all the tasks I needed to, but I had to force myself. I however did not workout because I could not bring myself to leave the house. This is depression.
I welcome any comments on how others deal with depression. I also want to know if you have found any natural alternatives. The anti-depressants scare me. Please share.
