Lack of Sleep Anxiety

I didn't sleep well last night, and I payed for it today. I tried getting out of bed around 1:30pm (I finally fell asleep around 1am) and I ate breakfast. I tried reading in bed, but it was torture. I started having an anxiety attack because I wasn't trying to sleep. So I closed the blinds and tried to sleep. I don't know if I did or not, but at least it made me feel better. My back was hurting, my legs hurt, so I didn't go for my walk today. I didn't even leave the apartment. I know I took a nap from like 5:45 to 6:30, but that's the only sleep I know I got this afternoon. Hopefully I will sleep well tonight and not have a repeat of today. I got a bit of energy around 4:30, but it quickly drained away. I should have gone for my walk then, but I was scared of making my body hurt worse. I need to get out tomorrow... I can't be staying in bed all day again. I have no idea why I freaked out today. I was just so tired that I couldn't imagine doing anything other than sleep. Even now I feel like crying I'm so tired. I just want to sleep. I think I will just keep this short.
Mood today was okay... when I was awake I felt okay, even with the anxiety. When I was asleep I felt fine. I didn't have any nightmares. Food today was good... I was in my calorie range and everything. I had my mini bagel with peanut butter for breakfast, some rice and sauce for lunch, a pork chop and potatoes for dinner and ramen for a snack. I should have had something lighter than ramen for a snack, but oh well. I'm in my range, and that's what counts. Anxiety was high today because of the lack of sleep, and sleep therefore wasn't good. Now I'm going to go try and get some more sleep.
