They are not brave. We are brave.
My very close childhood friend went OTD. He, like so many people here, was not satisfied by his wife sexually, couldn't control himself to keep his eyes to himself, always lusted for more. He had emunah questions, but he didn't seek out answers - he just wanted all the questions. He was so empty inside that he turned to drugs. He started neglecting his job. So at some point his wife gave up, took their two kids and left him. That's when he just slid all the way down. He was left with nothing, living himself in an apartment without a job.
It's not easy to be frum in the world we live in. It takes courage. It takes conviction. It takes thinking and introspection. It takes discipline. It takes a search for the truth. But it's the most beautiful, meaningful, and fulfilling lifestyle humans could have ever invented in a lab if they tried.
But more importantly, it's the life to live
because that's what the Creator of this world intended for you and intended for me.
Now, it takes time and work to get to that realization, but you can get there.
If you have specific questions that are bothering you, know that there are tons of resources out there to help you get a better understanding of those topics.
But since it seems like you're in a place of hopelessness, I think a good, lighthearted place to start is this hilariously funny but also extremely on point shiur by
