I, too, have had doubts and when doubt is placed in the mind it tends to conflict with faith. I believe it is okay to question -after all that is part of learning and growing. However, I think it is important to remember who the source by which that doubt comes. Listening to anti groups is probably not the source by which finding truth to your questions should come.
Seriously. I have never been able to understand why people who become disaffected by the church spend so much of their time trying to take others with them. I have a friend who left the church and spends so much of her time bashing the church and writing articles and etc. criticizing the church. To leave is her own choice but I don't get why she doesn't just throw herself into good books and work at other things of far greater value that would bring her so much more joy than to be so critical of a faith that teaches people to do good and be good and to believe in and follow Jesus Christ who taught us to do good and be good. What's so bad about doing good?
Let's look at things logically. 1)Those who are planting doubt in your mind are anti-mormon/anti-religion who spend so much of their time trying to tear others away. What good does that do? Why are they so emphatic about it? 2) If the church is "wrong" then were you a worse off person for following its teachings at the end of the day?
One thing I can tell you for sure...that when I put my trust in God, nothing wavering (James 1:5-7), that understandings and knowledge come to me that could not come by any other means. My understanding is quickened to understand principles associated with whatever I am learning (scientific or otherwise). When I doubt, my understanding slows and becomes a stumbling block to growth unless I use that doubt and seek out answers through legitimate means. Also...one day as I was doubting and picking apart the scriptures I was reading in my head and being very critical and unbelieving about what I was reading - I looked over to my Dad whom I have great respect and admiration for. It occurred to me that if I denied the gospel I would deny the priesthood and I had seen the power of the priesthood work many times in our lives before. I could not deny that power. It is real.
I was told a story once about two barking dogs. Both wanted feeding. The dog that survived was the one that was fed. Be careful which dog you feed.
Testimony should be derived from faith. Experiment on your faith by feeding it. Find out for yourself by applying principles of the gospel.
I, too, go through seasons of doubt. It is important for me to REMEMBER my blessings, past experiences that built my faith, to be grateful, to have charity and love. Faith brings me peace. Doubt brings me confusion and fear. Just REMEMBER the source by which your doubt or peace comes.
All my best to you.
