You sound like quite a survivor! I can totally relate, as I was in a cult too, and when I left it I was very lost. We humans all need to have a sense of the meaning of life and what our purpose is, and what standards to live by. Unfortunately, the culture we live in isn't too helpful, not to mention, it's constantly changing! What was "true" and "right" a century ago, or even 10 years ago, has completely shifted. This is confusing and doesn't lend itself to building a solid foundation for life. One message our culture is promoting currently is that you can make your own truth. Well, that doesn't make much sense, because if my truth conflicts with your truth, then which one is really true? Another message is that you should look out for yourself above others, and seek happiness above all other pursuits. However, that usually causes us to hurt others and become very self-centered. That's the opposite of what God teaches us in the Bible: to look out for the interests of others, and to pursue a holy life above a happy life. I've found that the most fulfilling life happens when I'm doing things for others, connecting with people at church, reading the Word, etc. Do you want love, joy, peace, patience, kindness, goodness, gentleness, and self-control in your life? These are the benefits of life in Christ. I'm not trying to preach to you, just to tell you how I've found my solid foundation, truth that is absolute because God made it (rather than the subjective truth that every person makes up for themselves), and I've been set free from a bunch of lies that made me hate myself, look down on others, harbor unforgiveness that only made ME miserable, and think that I wasn't good enough to be loved, hired, or included. Some of these resources helped me a lot and I hope you'll check them out:
