Hello Christopher1990: It has been said that enlightenment is a journey rather than a destination. Personally, I don't believe there is any way anyone can tell you how long it will take before you begin to notice positive results from your meditation practice. But kudos to you for your determination! There are simply too many factors in play. However, the Skeezyks will suggest 2 things you might consider.

Meditation is, from my perspective, a goal unto itself... not a means to an end. Having said that, though, one of the benefits of meditation is simply that it helps one develop the ability to be present with whatever is happening in one's life at any given moment. This then enables one to strive toward developing more lovingkindness & compassion for all sentient beings.

One of the "fruits" of this practice is that you become more aware of how you react to people & to events in your life. This doesn't mean if someone says something that "gets your goat" you won't feel hurt, or perhaps angry. But it means that, as a result of your self-awareness, you'll have more capacity to stop, breathe, & consider how you want to respond rather than just "shooting from the hip" so to speak. But note, this is a long slow evolutionary process... a journey... not a destination. Even those who have been practicing for years & years still don't get it right every time. I wish you well...
