Dear Sadness,
You're not a good companion to have, but yes of course, you are one of those feelings that make me human. So, I let you in. Tell you what. You are not welcome to stay.
Here we are, it has been months of on-off seeing each other. You're back again, and it has become obvious that you wanted to stay longer. I really wanted to kick you out of my mind, out of my life every chance I get, but it appears that you have grown stronger after depleting my fuel of enthusiasm for a good life. You became vicious in your attempt to cut me off from the people and things I love. I have to stop you now.
I'm giving you a hard time. It's obvious I'm still functioning, though I'm always sick and tired. I'm armed with faith, hope, and love - cheesy as it may sound, but they have been good companions throughout my life. I have a treasure trove of good people in my life, too. Some of them are helping me beat the hell out of you. You are just an episode, not my entire life. Pack your things, and go. Now.
Me
