Sounds like you need to be knee to knee with another bassist. First choice is a bass instructor. Second choice, a friend that knows how to play.
Fundamental things like how to tune it, how to hold it, how to sound a string - fingers, thumb, pick or what, how to mute a string have to be learned. Then things like where are the notes on the fretboard. How do I know which notes to use. What do I do to play a song? What's a bass line and how do I make one. You will need 4 or 5 go to bass riffs, who is going to teach you that?
Bunch of stuff you need --
www.studybass.com is a good place to start. An instructor will get you there in half the time it will take you to wade through what is necessary by yourself.
It's not rocket science, but, we all need help right at first.
Good luck.
