Why do I find my brain racing up after a session of meditation?

Name: Meera Date of Birth: 7th April 1998 Place of Birth: Jaipur Time of Birth: 6:50 AM

I have began to meditate daily hoping to neutralize my mind but it has not assisted. My mind is not going where it wants, I am even more tired than before. I will not be able to appreciate the calm of which everybody speaks. I am also wondering, does my birth chart have something that is not allowing me to rest, perhaps it is Moon or Mercury? I do desire to somehow hush down my mind and take my peace, and then I hope that astrology can give me the way.
