I need advice

Well I choke a week ago now on water might I add, and I have never had a fear of anything revolved around eating and drinking before. But now I cannot seem to shake this anxiety that I’m going to choke and be unable to breath again the incident was maybe 20-30 seconds felt longer because I panicked.

But idk how to get over this or if it’s going to go away any time soon. And it really sucks.

I wanted to see if anyone had an advice for me?
