The process of meditating is similar to building your fitness through sports, or learning to play an instrument. You will only experience the effects if you practice and keep this up for quite some time. The degree and time in which you experience an effect differs per person. There are people who notice strong effects after the first time, while others notice mild effects after two weeks or only two months. Please give yourself the space and time to investigate this yourself. You will almost certainly experience positive effects in the long run.
