Potential Miss-usage of Klonopin (Clonazepam)

I was prescribed Clonazepam last week by a psychiatrist. His instructions were to take up to, no more than one .50 mg tablet when needed. I find, however, that as soon as the Clonazepam wears off, I begin the vicious cycle of anxious irrationality. I have been taking only one .50 mg tablet per day; however, sometimes adding a half tablet to help sleep. I don't feel drugged... I don't feel like I'm abusing it, the truth is I just feel like I can stop obsessing over things that aren't necessarily relevant, and do things like read books and have normal conversation with people. I feel like it is some sort of miracle drug for me, and a further note... my life has been so negatively altered due to drugs like adderall in the past that I've become a huge advocate of any form of therapy other than prescription drugs for mental health.

I know Clonazepam or Klonopin are virtually harmless as far as health, but should I continue taking as is? Or deal with the anxiety for a few weeks until my next session?
