Botox increases/causes anxiety??

I have never been an anxious person. People would often comment they don't know how I barely ever feel anxiety. This all changed when I got Botox.

The first time I did it was around 4 months ago. A few days later I felt a ton of anxiety and didn't know what was going on. I felt like it was hard to breath, hard to swallow, and my throat felt extremely tight. I went to the medi clinic (almost Emerg) and got a few tests done and nothing became of it.

I just got it again because I loved the results the first time round, but realized after a few days that this is the source of my newfound anxiety (didn't connect the dots the first time). I have had to leave work meetings because it is so overwhelming, scared to book flights for travel (which I've been on so many and have never had any sort of issues), and am scared I will randomly get a panic attack around people I know.

I absolutely love the results of Botox but will never get it again. I am hoping this anxiety leaves me as the Botox does because it is so uncomfortable and I cannot imagine living with this consistently (its been about 10 days and it's not getting any better).

If I dig deep I find articles about this happening to others (extreme anxiety and/or depression after getting Botox), but some also say it can help with mental health issues. I would like to note also that I was 0% nervous before the procedure as I don't have any issues with needles so that didn't cause anxiety on its own (I got 25 units). Has this happened to anyone else??
