"You'll never be happy without God"

The anxiety is really bothering me tonight (as it does most days) and I'm again stuck in the loop of "I'll never be happy, never figure shit out" etc. Whenever this happens, I can't help but think of all the times people (mom, Christian school teachers, pastors) told me I'd never be happy if I sought happiness anywhere but in God. My one high school teacher used to say, "If any of you aren't saved, my prayer is that you're miserable until you find God." Such a shitty thing to say, but on my worst days, I wonder if I'm missing something-if maybe God IS the answer. I hate how much the indoctrination still has a hold on me. I have days where it doesn't bother me, then others where I'm sick to my stomach over it. I'm in therapy, I'm trying to work through this (and horrible anxiety in general) but I can't help feeling like I'll get over this and be at peace.
