Oh Sweetie!
You are definately posting in the right place as far as I'm concerned. I've been dealing with some of the very same issues lately. Maybe if I share a little of what I'm going through, and what I know about it, it might help? And please, if I'm off base tell me to hush,
I don't mean to imply I know everything you are going through, but my jaw dropped a little reading your post it sounded so familiar.
I know what time I got home last night and what time I went to bed, but somehow the things I actually did don't seem to justify the time span. My professor has been loading on assignments - somed due the next day, some due in a month, some things we won't actually be able to solve, but he wants us to try so we can figure out WHY we can't solve them. And I'm pretty sure I spent 2 hours last night sitting in a chair in front of the (unplugged tv) staring at my notes and not reading them. I'm blocked, no question about it.
I recognize this state from the last time I was in school - I just shut down and let go, basically gave up. At the time I wasn't able to get perspective on what was causing it. Thing is, this time I know why I'm blocked - I've just applied for grad school, and now I wait to hear if I get in. And I'm scared bloody senseless that I won't, and all my hopes and dreams hinge on it. I am so not in control of the outcome and it freaks me out.
So in a sick, pathological way, if I just shut down and don't do the work, I'll fail, but I'll be in control of my failure rather than failing on someone else's terms. And the other part of it is that I worry that I won't get in because the apps committee will think I'm a failure, and that creates a wierd inmpulse to proove them right, when in reality they may not be thinking that at all! Sick huh?
Is there something deeper that is troubling you? You said that you are back in school, that you gave up before. Hun, is it possible that you've somehow convincing yourself that you can't do this because you've "thrown it all away before"? If you can, you absolutely have to let go of what happened last time. I don't know you, but I do know that you are not the same person you were last time you were in school, and you are not destined to the same outcome as before.
By all means, cry if it helps - sometimes I just get so much stuff built up that crying acts like a release valve. Can you talk to your prof about giving you time to catch up? Or maybe try to study with a friend? Thats one of the things I'm trying to do.
In the interest of full disclosure, I have to say that the main reason I'm able to get a better perspective on whats happening to me this time is that I'm treating my depression. I can actually feel the difference between "normal" and when I get stuck and my brain goes away. Before I was getting treatment, it all just kinda smushed together.
I'm so sorry that you are struggling. Please know that I care.
