Why does religion consume my life???

Religion is just driving me crazy. Most of my family are Christian and I would love to have strong faith like them but doubt seeps in all the time and I look at other religions and its like, how come Christianity is the only one thats right and completely invalidates all of these other religions? If I lived in India or something, their country's religion would probably be doing the same thing that this country does with the vast majority being Christian in saying that their religion is the right one and all others are the wrong one. I look into different religions a lot and on some days Christianity does make sense to me and on other days, it just feels like a crock of you know what. I just really wish religion would completely disappear because I hate having religion consume my life and what can I do to just get religion completely out of my life before it makes me completely freaking loco? Thanks in advance.
