Loss of "faith" in buddhism I've never had any religion throughout my childhood and adolescence, and at the age of 18 I had my first contacts with buddhism; It seemed fascinating, and I kept reading about all the things I could find about it. Everything just seemed right, because I was truly convinced by this idea that the truth lies within, and I just saw the buddha as someone who had found it. It seemed to be the "no trust-my-words religion". 

Recently I bought a buddhism book. It was an interesting reading, but somethings were discussed that I haddn't seen with this emphasis: karma and rebirth in other worlds. 

The thing is that, after that, I became VERY skeptical when I learned that those things come from hinduism. It seems to be the religion that existed before buddhism, and it has karma, it has the samsara, the liberation (which is a little different), the worlds, the gods... And it's just seems as though the current culture at the time and location buddhism took place influenced buddhism itself, poisoning it with the same kind of dogmas other religions have - man-made dogmas, made up truths.

In short, my problem is that following buddhism started to seem like following christianity, or islam - just another religion that it's followers think they are right and everyone else is wrong. Why is buddhism any different? It seemed right, now it feels overwhelming and almost crazy. I want to follow buddhism, but those hindu concepts make it become yet another trust-my-word religion. I'm seriously disappointed.
One of the beauty about Buddhism is "Don't just believe, but find the truth by yourself" (as I paste below).
