How do I know I'm doing the right thing?
For example, I'm in a relationship with a Christian girl.. we've been together for about 3 years. She recently brought me to God... but when I gave in to God, 'Leave Sara' went through my head. So I had anxiety, I was throwing up, etc... then I finally left her- but the anxiety was still there. So we got back together, but instead took a break. Then my mother said a few things... like how in the Bible it says 'Leave thy father and mother and go to your spouse'- that doesn't mean never talk to your parents, or cut them off. So I got out of that, 'Focus on God', and the anxiety was gone. Then a week later, the anxiety is back. So I surrender to God, and prepare myself to stay with her or leave her, and pray for an answer. I felt fine at that point. Then I decided to think about what has happened... God has blessed our relationship in many ways... and if he wanted us apart, he would've made it clear. So I decide that I'd stay with her. Everything is great. Now a couple days ago, anxiety is back.
My mom says that if I made the right decision, God would give me peace. But I still get the 'what if I made the wrong choice' and all those doubts, so I end up with anxiety. If I made the right choice, why is God not giving me peace? Is He testing me? Or is it possible that I just have problems in my head... some sort of anxiety disorder or OCD, and this has nothing to do with God? This is why I'm lost.
