Ahhh I totally know what you're talking about! My anxiety gets in the way of me getting stuff like papers and presentations done. When I try to start working I get overwhelmed and then all I can do is think about how much I have to do and how anxious I am.

Breaking things down into little steps does help. It makes it seem like less of a big deal if you have small steps that lead up to the big end product.

I also really have a problem with procrastinating. I've found that the farther ahead I start something, the better (although getting started is always hard...). This helps to keep my anxiety level down because the deadline is so far away.

Hope this helps and good luck!
