Vision blackout

I've seen a few posts from years ago under anxiety about this, and I never thought it could be caused from anxiety so I'm wondering if anyone else experiences this

There will be moments ill get ice pick headaches and it'll black my vision out for 1-2 seconds. The first time it happened I had a migraine and it done it so i figured maybe thats why. I was worried it may be something neurological and regardless I'm going to bring it up to my primary, but it's happened 3 times today, once yesterday, and twice with a migraine a month or so ago. The increase in frequency is worrying me, but I wonder if it could be a weird symptom of anxiety or if it likely is something neurological. (even if its just migraines causing it) I get a bit dizzy, vision laggy, and lightheaded but not like I'm about to faint with it.

(Not looking for a diagnosis, just genuinely curious because it would have never crossed my mind that anxiety could cause anything like that)
