Is 155 over 115 a high bp reading?

I am a 40 year young female. My bp used to always be 110 over 70. For the past three days it has been 155 over 115 with a headache and dizzy spells and overall fatigue. I am on Cymbalta, Klondipin, and Wellbutrin treating post tramatic stress disorder and clinical depression. I am scared i may be having a heart attack, but it could be panic. Should I go to the ER for a bp reading of 155 over 115? I have no insurance and don't want to be mistreated...
