Im So Confused About Religion!?

Ok, I am Jewish currently since i was born jewish and I'm a teen. My best friend is christian and one night we were talking about our different beliefs. I was barmitzvah'd, but still don't know a lot about jewish or christian religion. My friend said that if you don't believe in jesus you will go to hell. Well, obviously i don't so I'm scared if the jewish religion is wrong because hell sounds horrible. Now, I understand christians and jews are almost exactly alike. We both believe in THE SAME GOD. The only difference we have is we believe the old ways, and also we believe the messiah is yet to come. In fact Christians were once jews before jesus. I was thinking about the messiah and it hit me. The main connection with the messiah is to get a closer connection to god. If jews have a direct strong relation with the same god as christians, and christians have a relation through jesus, this means we won't go to hell because of our relationship with god in all. Does it all come down to that? Also I understand we have free will, but why wouldn't god try to help us in tough decisions. Like, if there is an anti messiah, he should tip us in and put instinct in our brains. basically perform miracles all the time, and lead us all to heaven. Plus, Hell Sounds like a horrible place, so why would god allow there to be a place as such? Doesn't he love his creations? It's like (be a bigger man) and if someone sins still bring them to salvation and teach them the right way. Why would angels bring you to that horrible (evil) place. God allows and (correct me if I'm wrong) creates hell for sinners, but it seems so evil. I also understand Jews don't believe in hell. Does that mean we believe in some other bad place or all people go to heaven. Another question I have is about the end of the world. In christian religion it says that seven years before the end they will go to heaven. Then the "anti-messiah" will come (which would be jews first messiah possibly) and bring 3 and a half years of good and bad. First of all, will it hurt when the world ends. Will i feel pain of lava pouring on me or will god make it painless. Also, within the seven years if we decide to follow christ, is it too late to go to heaven within the seven years? If this whole anti-messiah thing is true, god should do that to build his people, and make a big peaceful heaven for all its creation, cuz if christians start dissapearing into the sky, we will probably convert to cristianity. Next I still don''t understand why Jews didn't believe Jesus was the messiah, or why christians believe he was the messiah. I guess the Jews believe that he didn't complete the specific tasks in the torah, but if jesus created miracles and blackness and earthquakes when he died, why wouldn''t we believe him? Also, how can something as big as darkness and earthquakes be mistaken. If jews don't believe of the darkness when he died and whatnot, then thats a hard thing to mistake or not write down. This goes the same for christians. how could they mistaken nothing for darkness etc. Someone's got to be bluffing or misleading history. So I ask you to please respond nicely on both points of view and not be racist or prejudice about Jews or Christians, because in essence Jews, Christians are practically the same and believe in the same god.
