I hear you on fear of failure and having deadlines. I am in school as well. If you have not already, consider making a list of everything you need to do.
FREAK out!!!

Then allot time each day to complete tasks. I try to only look at each day's tasks so I keep the overwhelming feelings down. When you start crossing stuff off the list boom, success, success, success. Focus on those. It will still be stressful, but it helps to manage it.

I hope this helps. It took me nearly 10 years to complete my undergrad. I have become pretty good at balancing my time and stress, working 10+ hours a day depending on where I was on my deployment schedule is more art than science!

It can be done, you just need to take it one day at a time, looking at everything will make you crazy!! We both know that doesn't help an already stressful situation!
