Hey guys. I'm in need of some advice here. 

I'm not diagnosed with anything and never really have been, but for the past month or so I've had an underlying anxiety to my life and ultimately this past week has been debilitating. I've looked into going to a therapist but that's not going to help in the moment so I'm wondering if anybody has some tips for getting yourself under control for a bit. 

I have been super stressed with work and I have finals for class coming up so I really need to focus on getting my last assignments done and not falling behind at work. However, I've had almost constant anxiety since last week. I sleep like crap, I can't seem to focus on anything. I feel sick at times and I'm generally not hungry. If I have 30 minutes before class I generally like to get some hw done but I've just been pacing back and forth having trouble getting myself to sit down and type some words. 

Therapy isn't available til next week which is inconvenient because things are due before then and finals are next week so it feels like getting there is so far away, and that's not considering the fact that an hour conversation isn't gonna solve my problems. I was hoping somebody has some advice on how they are able to calm themselves when they feel overwhelmed and need to get things done.
