if i have anxiety disorder and because of my excess worryness i am getting some unwanted side effects like headache, high blood pressure and insomnia 

so than i went to doctor and lets assume doctors prescribe me best anti-anxiety medications which have 90-100% success rate(just assume) 

so than my medications is working effectively but because of my current life situations and my pessimistic personality i am still worried about my situation, so is i am still in anxiety mode..?.. and does my unwanted symptoms of anxiety will go away..?...does the goal of medication is to make you  worry about nothing so your symptoms will go away...?
