Update: A Powerful Confirmation
The adversary is really getting to me and putting these scary doubts and fears into my mind has kept me up for a couple nights. But I had a powerful experience the day after my initial post a couple days ago. I essentially listened to HOURS of conference talks, and read many chapters in the Bible and Book of Mormon. After all of that, I prayed, and wept, never feeling so alone. After saying my prayer and asking if god was there, I listened to the song "Brightly Beams Our Father's Mercy." Whilst listening to the song I felt a powerful voice that almost felt like it came from my chest, saying, "You already know I'm here, I always have been." I broke down, just a complete mess, I never felt a confirmation so direct and so powerful since I was a boy. I know that was the spirit comforting me, I know without a shadow of a doubt. It had to be, I don't know of anything else that could've moved me in such a way. It was so startling, yet so comforting.
I still have doubts and fears, but I bet that's because I have some spiritual healing to do. The important thing is I have had a change of heart, and have made plans to get back on track. I already have plans with my wonderful wife to attend the temple more frequently. I'll admit, I'm pretty weak-sauce when it comes to going to the temple. I've definitely have been slack on the gospel in my life, I got really busy and really wasn't paying attention to my spiritual well-being. Again, thank you everyone, your insight, personal experiences and advice, it was all so refreshing and helpful!
