Hi! Im 17kyu, but i havent playd in a looong while, and just cant win anything anymore 
Are there someone who would help me?? 
If you are rusty then there is probably a lot of intuition you have forgotten about. Just play 10-20 games and don’t worry about the rank “correcting” itself to take your lost memories and skills into account
However, I’m happy to play a correspondence game commenting on the game as it develops. I’m just ~12k but hopefully there would be some useful pointers I could share. Send me a challenge if interested.
