when you feel too anxious to do anything, what will you do?

Just try to relax. One step at a time. Make it a habit to put at least an hour of play or rest in your schedule. Try to plan ahead and sketch out your activities. Prioritize and make room for some time for yourself. If things are too much for you, it's best to ask help from friends whom you can count on. Just take it easy and don't put too much pressure on yourself. Your requirements are pretty much giving you that pressure already. Just breathe when you feel so stressed and you don't know what to do next. Stay positive and never let a failure keep you from proceeding to your goals.

I also find it hard to do anything well when I feel anxious about it. Usually I still try to do it patiently and keep telling myself to calm down instead of thinking too much of it. Otherwise it would affect my working speed on the thing that I am working at. Like the saying goes, "The more haste, the less speed". So you may try to find some easier ways to complete your paper. I would like to say that you need to think of some guidelines or outlines for your topic after you have chosen the topic for your paper. Then list out some key words and topic sentence for each paragraphs and give as many examples as you can to state clearly on the topic sentence of each paragraph. Finally, make a short summary to end your paper. Stay calm and feel good.

I do what I can to really take a deep and calming breath. I really do buckle myself right down and really just throw pretty much all caution right to the wind and really do what I need to do. A lot of the time, I just feel like I just need to focus on one thing at a time. The other things are important, but I'll get to that when I get to that. Make a list. Do one thing. Take a short break. Take another breath to say the very least. Do the next thing. Try and not let everything get to me. Granted, that is really just going to be easier said to done to say the very least. There are times where our focus gets diverted, but it is often going to be an uphill battle for many people.

Take it easy. Mild Anxiety is helpful because it enhances learning, but if it accelerates, that is not good. It can affect your thoughts process. You have to do some stress debriefing relaxation. Try to do some Deep Breathing Exercises.
