This is a tricky question to answer since not every problem is the same, and not every person approaches faith or doubts in the same way.

However, pretty much all attacks on your faith are based in some kind of contradiction, and it is usually best to start by identifying it.

1. If the adversity you're dealing with is some kind of prolonged difficulty, the problem could be a contradiction between your belief that the gospel is supposed to help carry you through problems, and the realization you're still hurting despite it.

This may cause you to begin wondering if you're failing at the gospel, or if the gospel doesn't really have any effect on the real world after all, or if God just doesn't care about you.

2. If the adversity is a temptation you've succumbed to, you may naturally feel like you have to justify your action so you don't or feel like a bad person. The contradiction here is that you don't really feel like a bad person, but you believe the action was bad. You don't

...really feel like you're under condemnation, so does that mean the rule you broke isn't really as bad as the church told you? Or does it mean you're not very good at feeling the Spirit anyway, because you're not as good at the history as you thought you were?

3. If the adversity is a disagreement with someone over church history or doctrine, the contradiction is usually that someone you believe is good did/said something bad. Joseph Smith married a 14 year old, for example - does that mean the prophet did something wrong? Does the

...church expect me to accept that an adult marrying a minor is okay? Did Joseph just tell people God told him to do it so they wouldn't question him?

You may have noticed by now that almost every case presents two opposed options - this/that, yes/no, good/bad, right/wrong. These are comfortable, reasonable ways to see a problem.

But they're most likely wrong.
There is almost always another option.

1. A prolonged difficulty doesn't have to mean you're failing at the gospel OR that the gospel doesn't really work. The third option is that the gospel was never meant as a get-out-of-problems-free card, but rather as a method for taking advantage of the difficulties that arise.

It may be that God is trying to show you that blessings aren't usually something you earn. Or teach you how strong you really are. Or how to be more grateful.

2. Committing a sin but not feeling bad does not mean you're just a bad person OR that the sin isn't actually as bad as they told you. The third option could be that feeling bad isn't an automatic consequence of sin, and God expects you to know the rules and follow them yourself,

without needing a slap in the wrist to tell you bad things are bad. It may be Heavenly Father doesn't want you to berate yourself over the fault but rather build yourself up and be better.

3. A challenging piece of church history does not have to mean choosing between loyalty to the church OR trusting in historical evidence. In virtually every case I've seen, the third option here is that there is important context and other information missing from the story.

Or the third option may be to admit you don't know how a piece of information fits into your testimony, and that's okay. You have had spiritual experiences which convinced you the church or Book of Mormon was true - fall back on those experiences if you need to. Even if you can't

...feel the same feelings now as you did then, remember that you did feel it then. Look through an old journal, or old sacrament talks or Sunday School lessons you prepared. Let you bear testimony to you.

In conclusion, my advice would be drill down to understand what the underlying problem is and why it bothers you. Then look for the third option. Or the fourth. Trust that there is an answer to your questions. God sees a much bigger picture than you do, and He will help you.
