Can caffine come off the wrong way if you suffer from high anxiety, stress, and depression. I almost never drink coffee. But i had coffee from dunkin donuts today just black and i was fine. And then a couple hours later i had another. Both were a small cup. No sugar just black coffee. My second one i added cream. But my second coffee it started making me feel really paranoid and weird then walking home i felt like i could easily trip over anything cause i felt alightly a bit unstable to walk. For what reason i have no idea cause im only 22 years old. My blood pressure is always 140 plus because i got to much going on in my life all the time.
