Tips on climbing

Anyone recently climb out of silver/gold? I was gold 5 last season and having issues getting back. It took me a while last season and the season before, so just looking for a way to speed up the process or fix something I'm doing wrong. I started this season silver 2, dropped to like silver 4, got up to silver 1, now at silver 3 and could get demoted again if I keep this lose streak up. I don't know if I have a change in gameplay or if its just bad luck? But these lose streaks seem to come out of no where, and I take breaks between just to come back the next day and lose again. I guess this is a half rant / needing tips. Anyways, maybe looking at my match history or just info that helped you or things you've done to help the process. Thanks!

tl;dr: pls help
