Samhain Releasing Negativity Ritual

So, glanced through my new books and googled around online a bit for a friend and have noticed releasing negativity is something quite common to be doing during a Samhain ritual. I think I need that right now. I have been very depressed lately, even called in sick to work twice this week just because I didn't want to be bothered with people or the world in general. I just feel like shutting out the world for a while...I don't really know why though so I really hope I can relax and this ritual, along with focusing on the things I do enjoy in life, will help lift my spirits a little....
