Hey Jolz, i think I know your problem. Meditation is difficult at first, it's just like anything else though, with practice comes perfection. You just need to meditate everyday for at least 10 minutes, even 5 if you find it too much.
Also, after reading your post, you seem to be overthinking the situation, which meditation is the EXACT opposite. There is a quote from zen teachings that I love, and should help. "Zen philosophy is to not ponder life and existence while peeling the potatoe, Zen philosophy is to just peel the potatoe."
Get it? Don't think about meditating, the spirituality behind it, let all things go, let your conscious go blank, and enjoy the sweet bliss that is experiencing the purity of just existing.
When meditating, focus on your breathing, inhale for 3 seconds, wait 3 seconds, then exhale for 3 seconds. Focus on it, and when a thought comes in your mind, interrupting the process, don't force it away, simply be aware of it being there, and forget about it.
I realize the last sentance is confusing, not forcing it, but at he same time just letting it go, I didn't understand it until a couple nights ago, when I realized forcing my eratic thoughts down was simply making meditation harder.
Simply let go of everything......
Also, If you are meditating while experiencing a lot of negative feeling or worrying about day-to-day things, it will be much harder.
Hope it helps
P.S. been meditating for over a year everyday for 15-60 minutes.
