Meditation is good, and my story is kinda like yours, except I'm older than you, just turned 65. I've been telling myself lately that I need to get back into meditation too.
As for your thoughts you mentioned, don't try to make out your thoughts, don't try to define them in rational terms. It's not a rational experience so much as a spiritual experience. You must let your thoughts flow and move through that part of your mind, move out of your mind.
The eastern cultures are much more spiritual than the western cultures.
