I know exactly how you feel. My hair has been falling out and I have been having some anxiety too. I'm a normal person, or was before all of this and now feel on edge more than usual. It comes and goes for me. Some days I'm fine and then when all of the pressure comes on I start going through the cycle again. What has been helping me is to get away from it...even if it's something I have
to do at the time. I just walk away and do something else for a while to keep my mind off of it. I made my husband take me out tonight even though I have a test Wed. and should have studied for it. I needed to get away from my books so I could decompress. I also do a lot of deep breathing. I know this all sounds nutty, but that is the reality of nursing school sometimes. Take a long hot bath, have a cocktail :beercuphe , lol, spend quality time with family and friends and get out of the house more, even if it's just to take a trip to Wal-Mart, read your bible, recite some daily affirmations....anything helps. I created a blog where I can vent all of my frustrations. If it makes you feel better knowing that someone else out there is going through the same then check it out. http://my-journey-as-a-student-nurse.blogspot.com/
Just remember that you're not alone. You can do it and you'll get through it. Good luck.
