I need tips on learning the Ukulele

Helloo, i've been trying to learn the ukulele by myself now for a few months, but i still can't get the hang of it. I tuned it already and it sounds good but whenever i try to play a song, it just doesn't sound like how it's supposed to sound :( i'm struggling on strumming too. If you have any tips on it, please let me know :) i would really appreciate it!
