Oh my gosh thank goodness I just saw this post. I feel the same way!!! I am totally freaking out and can't focus on any of the work I need to do even though I rationally know that it's doable. I think it's an anxiety thing. I'm actually going to email my professor to ask for an extension just so to alleviate the anxiety I'm feeling right now - it's out of control.

You are not alone and it's good that you're getting help. I see my psychiatrist tomorrow so hopefully we'll figure something out. Let's you and I conquer this!
