They say that the first step in overcoming a problem is admitting that you HAVE a problem. So before you can deal with your midterm stress, you have to recognize it for what it is.
You might assume that you have some kind of long-lasting virus (fatigue, stomach trouble, heavy sweating) or that you've developed a neuromuscular disorder (headaches, a twitching eyelid). But it's just good old-fashioned stress (unless it's not; if symptoms persist, you should see an actual doctor). So how can you handle it while still juggling the responsibilities of projects, reports, and other obligations like family and work?
Yes, you're in grad school, so money is probably tight. But sometimes it's worth spending a little cash to get some peace of mind. So instead of trying to handle school AND the demands of daily life (I.e., keeping yourself and possibly others clean, fed, and clothed), outsource some of those chores!
If you have kids, a couple hours of peace to study or relax might make the money you have to pay a sitter the best $20 or $30 you've ever spent. Order takeout and drop off your laundry for someone else to do. All of these things require some expenditures, but consider them an investment in your sanity.
2. Look out for #1
Sometimes, what you really need to do is take a nap, go for a run, or sit quietly in a room staring at a blank wall. Even though midterms can be hectic, don't be afraid to be a little bit greedy with your time, and allocate a chunk of it to maintaining your own mental health. Flight attendants have it right: you have to put on your own oxygen mask before you can help others.
3. Don't be afraid to look for support.
Sometimes, self-care isn't enough, and there is absolutely no shame in that. Know what resources your school makes available to grad students and take advantage of them; they might include stress-management seminars, individual counseling, or other options. These services are there to help. Let them.
