How do you do it.

With the season coming to a close I've recently decided Id try to make a dash from B3 to at least silver, At the start it went relatively well even getting to skip B2 putting me at B1 but since then I've really hit a snag I'm stuff at 0 LP at B1. For every game I win I lose two more putting me back to 0, and I'm frankly starting to get really depress as I feel like i'm going no were at all let alone Silver by the end of the season. So I guess what Im asking, How do people get out of bronze. I hate to ask such a general question (and I suppose I deserve all the comments that are just gonna say git gud) but I just don't understand no matter how hard I try I can never seem to swing the game.
