So why do I feel anxious after I have practiced meditation?

I attempted to meditate so that I could enjoy my mind, but I find myself further agitated. I have never thought of astrology before, but I think that perhaps planetary positions could be the cause of my anxiety. I am nervous and self-congratulatory even in small social contacts. I would like to know whether astrology can provide me with instructions to feel better and confident.
