Hiya,
I'm a Christian and have been since I was 13. These thoughts might sound sanctimonious - sorry if they do, I certainly don't mean to be - all that I know of christianity has mainly come through sheer holding on when times have been really tough and yes I've been badly let down by church / other christians. It took me a long time to recover and start to trust those same christians with my deepest struggles and true self again.
Anyway, FWIW, my thoughts are - faith is not something people just have - so often I've heard people say "Oh, I envy your faith" but the thing is faith is a gift from God and not inherently part of who we are (or are not, IYSWIM!). I believe that if we ask God for faith and ask it genuinely, He will be thrilled to give it to us. It comes in an infinite variety of ways and over the years I've heard so many completely different stories of how people came to believe but the one defining factor is the real assurance that God has truly come and made his presense known in that person's life. Quite often it's a very long process which is almost imperceptible at the time but as you look back you can see how God was arranging the circumstances of your life, allowing you to meet people who would say important things to you, and sometimes touching your spirit (that might sound a bit airy-fairy but if you've experienced it you know it's real) in gentle but powerful ways.
Also - one of my fave prayers is by St THeresa and it starts "Christ has nobody now on earth but yours, no hands, no feet but yours" and the point is that most of the time God seems to choose to speak through other people rather than a thunderclap from heaven (although I've heard those stories as well and had a few in my own life). I've puzzled over why He does this and the one of the things I've thought is that he so wants us to be in meaningful and satisfying relationships with each other rather than isolated spiritual thrill-seekers (no man is an island and all that). So that's why, however inadequate your local experience of christians is, it's so life-giving to find christian friends who you can talk deeply with and share your concerns and heartbreaks with.
Don't want to bombard you with the Bible but Jesus said "Where two or three are gathered in my name I am there in the midst of them" That doesn't necessarily need to mean "church" in the traditional sense, it could be hooking up with a christian friend. On MN there are some fab christians who are totally honest about the highs, lows and in betweens of being a christian.
THe christian prayer thread would be one place to start if you want to ask others to pray that God would give you the gift of faith.
Another thing - "faith comes from hearing the word of God". The number of times God has spoken intimately to me through the Bible and answered exactly the prayer that is pressing on me by showing me what life looks like from the perspective of eternity. If you find traditional Bibles a bit off-putting there's a very modern translation which is still true to the original sense, called "The Message". You can get it on Amazon.
THe last thing - yes there are discrepancies (or mysteries if you prefer) and over time I've gone from being worried about them and feeling that to "believe" I have to have well-researched answes, to rather liking them. Whether dinosaurs existed or if there's life on other planets are the stuff of good pub chats with friends, not make-or-break-faith big issues. I guess (this might madden you) that as I've experienced more and more of God's presence in my life I've amassed a heap of personal evidence that God exists, that these questions can't even begin to compete with. That's not to say that I don't bother thinking about these things, it's just that I've come to accept that the universe is bigger than my brain and there are some things which are simply beyond me. I'm certainly not thick or thoughtless and I do love using my brain to seek out the best answers to difficult questions about faith, God etc (I love being challenged as to why I believe!) but I know that my answers are only partial and open-ended.
Sorry to ramble - HTH anyway, or sparks off some thoughts in you. CAT me if you want to talk about it any more. I don't mind at all if you disagree with every word I've said and I won't be offended by anything!
God bless
