Take a deep breath and calm yourself. Take a rest if you need it. A rest can't do more harm. Letting yourself go on even though you're tired will only bring more harm.

As you do your work, take one step at a time. Listen to calming music.

Trust me. I know how it feels to lose all sense of motivation. It was a terrible experience, but I know you'll get through it.

Don't pressure yourself. You will make it through. Perhaps, you need a little talk with someone. It is always nice to let it all out.

That is all I can say. I know the feeling is different for everyone, but I know how hard it is to not be able to do anything. You will make it. I know it.

First step is to calm down. I also have Anxiety. And there is help for this. Take yourself to any Pharmacy and ask them to help you locate a bottle of St.Johns Wort. It will help immensely to calm your anxiety no mater how strong it currently is. I love that it is NATURAL.
Also if you get occational migrains, I suggest you get a bottle of Excedrin Migraine Formula. This bottle does contain small amounts of Aspirin. The pain disappears in just a few minutes. Often I get them so bad I feel my head will explode.
