Do I have rabies?

[CubixX]

So I was visiting my sister's house and she has two cats a black one and a white one. And I was playing with the black one and it accidentally scratched me on the knee. This cat used to be a stray and got its rabies vaccine. I have serious health anxiety keep in mind. And my muscles start twitching all around my body a few days later. But I'm 14 years old and I thought it could just be a growing thing so I brushed it off. Then my neck becomes stiff a few days later which could be from my pillow causing muscle aches. And then one side of my throat would hurt which worried me. Today I was sitting on my bed usually crisscrossed and I must've been sitting there too long because my whole left leg aka the one with the scratched kneecap was hurting. And I feel like mucus was stuck in my throat. Should I get a vaccination or am I fine? Also I have had my tetanus shot. My family says I'm totally fine but I don't believe it. I'm scared I might die please help!
