welcome! I can totally relate to your story. it's really frustrating finding out you've been lied to, and you've sacrificed a lot to the people who bully you and lie to you and are quick to throw you to the curb if you don't submit to their control. it's like lots of types of abuse, I suppose. only worse in some ways because you can't see what it really is when you are too involved in it. Just learn from it, learn to check things out a little more thoroughly before getting too involved. Don't turn your anger on yourself for falling for any of it or for time wasted, and don't spend too much time being angry, it's not worth it.
good luck!
