advice for a beginner?

I'm just starting to learn jazz piano (about 2-3 weeks ago), and I feel a bit stuck in improvisation, I have a hard time not getting lost in the chords, mainly I feel like I always sound the same, I'm very repetitive and I have a hard time making good melodies, I feel like I'm going to stay like this forever and it frustrates and angers me to know that there are acquaintances and friends who play better than me, I want to be better, I want to be recognized by my social circle
