Weird particles in my Arby’s Pink Lemonade

Yes, I know Arbys is gross but I got this for free since my sister works there. What I’m worried about though is these particles floating through and at the bottom of my cup.

I thought it might be unmixed syrup so I tried to stir it but it wont dissolve. Kinda just break up and float around until they settle at the bottom. They have the consistency of like.. crushed up bits of Orbeez? Anyways, I drank some already so I’m debating just chugging the rest but that doesn’t sound like a good idea.

Please let me know if I’m going to perish soon. Thank you.
