Mini Stroke or Migraine?

-I want to start off by saying that I have diagnosed migraines and anxiety. However, I have never felt anything like this before

Last night around 12:30, I was on FaceTime with my boyfriend. I wasn’t stressed or anything. I was talking to him about a job that I applied for when all of the sudden I couldn’t talk. It felt like I passed out without blacking out. I was trying to say “attendent” but repeatedly said “attendance” then went silent. After about 10 seconds, I felt normal again.

The rest of the night I was having panic attacks. I felt foggy and light headed, but that was most likely due to my anxiety.

What could this be? I’m very scared. I’m 18 and fairly healthy.
