Hey

I'm an Atheist. As far as I'm concerned it's not that I am an Atheist because I "can't" believe in god or because "I havn't found the right religion yet", I feel settled in my worldview. I think that the world is in and of itself deeply absurd. So bouches of luck and suffering don't surprise me.
There are plenty of theological answers to theodicy- which seems to be your current inner conflict- maybe you want to read them up.
At the end, you can always escape into doubt, and I don't mean that from a believer's perspective. You can use doubt like a defense mechanism- never admitting to a certain opinion without adding a "but I'm not determined about that/I'm not sure". This attitude is no real constructivism in my opinion- because for that you'd have to have a subjective certainty about whatever it is you believe.
However, I think that even if it might be scary at first, at the end it is deeply satisfying and settling to make a conscious decision as to what you want, or are able to, believe, or accept as your subjective truth. Then you can still say "I know that I know nothing for sure" but you do have a subjective certainty. It's not doubt, exactly. It's accepting the ambiguity between never knowing for sure yet having an opinion.
For me, it took one year of intensive thinking about whether or not I wanted to believe in god, and at the end I made a conscious decision.
I'm a pretty ruminative or "philosophically" inclined person though- maybe it would be weird for most persons to dedicate so much time to this topic and such.
Don't know if one can really follow through my thought process- I tried.
