Tomorrow will contain a lot of ladder for sure, I won't stop till I'm back in diamond.
I may share some replays if I get lost or something, I'm sure someone here will be able to help me out.
PS. I think the cause of the demotion was that after getting into diamond I stopped ranked only played a bit but lost them mostly so from a 70%-ish winratio I went to 55% so in the diamond league i possibly had terrible winratio like 33%. I think this is the case. So the moral of the story is to keep laddering!
