Hi, things are spiraling out of control for you. This happened to me after the birth of my third child in Sept. I also run my own business and it started to fail because of my high stress levels and my inability to get it together. I'm a perfectionist and I think that my personality only makes this worse. I was getting dizzy, stressed, etc...things all started going wrong on me. Chronic headaches, left arm/leg pain, brain fog, anxiety, insomnia, my mitral valve prolapse was acting up (palpitations)..the list goes on....the stress of how I was going to handle my baby and other children in addition to my business was overwhelming. And it all started when my jaw got messed up again after having dental work prior to the pregnancy which acted up my tmj..then right after the baby I had to have my wisdom teeth out. All this caused mechanical problems and more emotional stress! This time I didn't just have jaw pain but I had the neurological symptoms. This on top of my new stressors made it spiral. Please don't end up like me, take control of your stress. If you need to, see a counselor. No doubt the clenching is making your trouble so much worse. I am trying a bite guard right now to stop my night time clenching. Only in the first week and it's not going well. BUT, I let this problem go on for way to long. If this is just starting for you I would advise going to a dentist and getting a professional splint made. The OTC ones caused me more pain. And I would consider lightening your work load at school and talking to your professors. Sleep deprivation can (and will) only make things worse. Initially I found taking Tylenol (just the regular) helped me to sleep and my dr. okayed this. I do believe that you can literally "worry yourself sick"...so try to take deep breaths and relax. I know it's hard...OH, and cut out the caffiene and watch your posture..Good luck...
