Hi I Am Trying To Decide If I Should Use

hi I am trying to decide if I should use pregabalin 75 mg for anxiety that I experience during stress.
I have ovarian cancer stage 4 and just found out I have a rare genetic mutation in braca 1. I start oliparip this week. ive suffered from this treacherous disease for nine years. I also have stress from an extremely disturbed ex husband in relation to slander,harrassment and emotional and financial abuse. ive read the side effects and am worried. I have a psyiatrist who is helping me to wean off other medication in order to start pregabalin. but im now wondering if I should just not take anything for a while and just see how I can cope. what do you think
