Farther Down

I'm so depressed now. I feel it. I have no energy. I'm just going to go into bed and lie there for a while. I got my ticket to see my mom today, so I should be happy and looking forward to it, but things aren't always what they should be.
Food: Had leftover baked ziti for breakfast, a Greek yogurt for a snack, a couple hamburger buns with some peanut butter for lunch and chicken and shells for dinner. Drank 32 ounces of Gatorade and so far 24 ounces of water. 
Slept from midnight to 9am, stayed in bed, got really pissed and had to tranq myself down, then slept from 1pm to 4pm. 
I'm thinking about moving out when the time comes. I don't think I'm fit to live with anyone. I'm too unstable. I'm not suicidal- just depressed.
