What do i do?

Today i was just sitting in my room with my friend watching TikTok when suddenly i got this bad feeling, my gut started turning and my heart started dropping, i felt like i was going to puke. I felt like something was off, like something was about to happen. I felt so ill. Im typing this now only 10 min after i talked to my friend and it’s still there. I don’t know whether to ignore it or not but for a feeling that I’ve had for at least 30min i feel like something is wrong. There has to be a reason i feel like this i just cant figure it out.
