I sympathize with you Fitzy. Life just keeps compounding stuff, until you suddenly have this huge pile of stuff that you have no idea how to dea lwith it. As the saying goes "The journey of a thousand miles begins with one step.". I know from reading past posts that you are a Type A personality, so it is in your nature to be stressed and to push yourself. I bet if you took it easy, you'd be stressed that you weren't relaxing enough.
Try to break things down into specific tasks and goals, and prioritize. If writing motions for the legal aid dept is more important than class work, by all means get some motions written. But between writings, take your dog for a walk and allow yourself to decompress. Even a 10 minute walk is better than none. If your supervisor is so great, maybe he'll understand that you need to cut back even more (unless it is part of an internship type thing that you need for college credits). You can do no one any good if you are so stressed that you can't complete projects. Get your motions written, then move on to homework (maybe with another walk in between). Study for your exam, but take another walk. Spending time out and about will get your mid off of things, if you let it.
I know you are in your last year of law school, and excuse me for my naivete, but does that mean that you have to apply for jobs while still in school? Would it be possible to let the job search take a back seat while you get yourself through the academic year? Or perhaps just put off applying for things until next semester?
Meditation might work, but if your mind is too noisy, you might not be able to relax. Try the relaxation thing, and when you begin to get anxious, maybe journal about why you are feeling anxious AT THAT MOMENT. Then try writing a few things that you are thankful/grateful/happy for. Positive things. I could also recommend a type of cognitive therapy that would help you (it generally works well with intellectual individuals) learn to cope with anxiety, but I think that at this point, it might just be a little much for you. If you are interested, it is called either REBT, or CBT.
I am not a Type A person, and I tend to let things kind of float by. I pick and choose what the most important things are, what I have the most control over, and I tend to focus on those things. I am dedicated to my profession, and there are licensing exams we have to take in order to gain more responsibility. For the past three months, I've been working full-time, dealing with my first ever flare, and studying for the highest level license test. My health is the most important thing to me, because without it, then everthing else is meaningless. So I spend the needed time to make my doc appts, cook healthy meals. Doing well at my job hinges on my health, so as long as I'm treating myself right, I am still able to excel at work. Yes there are days when I'm just dragging ass, but my co-workers know about my UC, and they accept I'll have a down day ever yweek or so. Studying for the exam was important, and probably the most stressful part for me, because they give you a very broad outline of stuff to study, which includes about 5 textbooks, 2 state environmental compliance manuals, as well as national regulations. When I took my test today, there were 200 questions, and it took me over 6 hours to complete it. I became painfully aware of my defiencies in studying pretty quickly, but I also realized there were parts that I knew better than the back of my hand. Instead of focusing on the stuff I didn't know, I gave myself credit for doing well (I hope!) on the parts I did know. I won't get results back for a month, but I'm not going to stress about my score, because at this point, I either passed or I didn't. If I didn't, I retake it in the spring (GOD forbid!), but I have a better idea of what will be on the test.
Okay, I just realized that I wrote a rambling novel for a response. Hopefully some of it made sense and had something useful that you can put into practice. For your own sanity's sake, take your dog for more walks! That in itself will relax you, and if you start feeling guilty for taking time away from your projects, remember that without taking time for yourself, you won't be able to do the projects anyway.
