I need advice............?

Christians would have me believe that i am going to Hell if i do not repent for my sins and turn away from them. They also say that anything in my life that will tempt me into sinning must be banished. This means i must find new friends, as they will tempt me into getting drunk and doing all that kinda stuff. Just the fact that they do those things is enough to tempt me. I must not give science any notice as evolution is an apparant myth. It also means that i cannot look at a really hot female as i may get thoughts of lust for her, and i cannot masturbate as i am lusting over someone whilst doing it. Society itself is a temptation as it promotes sex before marrage and its ok for girls to walk around in mini skirts and that. So essentially for me to be saved from eternal damnation, i must get rid of my friends, must be around my family as little as possible as they may tempt me, must not go out in public, must not lie to make someone feel better, must not drink and this will tempt me to lust and to get more drunk, and ask for forgivness everyday. The worst thing is that all Christians say that i am bathed in Sin as i have anxiety. My anxiety causes me to worry about all sorts of things. Being fearful is a Sin, therefore my anxiety is a sin. This is what christians who take the bible literally believe. I do not know what to believe..i need some opinions on all this?
