Fear of Facebook post seen 8 years ago

I am a 23F living in india. My mom and I are best friends since childhood and we do everything together. One day we were scrolling Facebook together when I was 15 years old that is 8 years ago. I was scrolling a facebook post/game that predicted people's death and my mom played the game. It predicted her death in 2020 June/July and in her hometown from a snake bite.

Now I've had serious anxiety issues related to that one incident. I used to do weird things to make deals with God to not make het die, like not watching porn ever or not eating chocolate. I got sleeping pills for my anxiety but I never really got any real help pertaining to this incident and I suffer from anxiety that I will lose my parents that they'll die. This covid fear has gradually increased my anxiety and these days I feel it's harder to breathe. I always have to gasp for more air like I'm not satisfied with the amount of air filling my lungs. I am currently fidgeting my leg while writing this post. Since early childhood I freak out when my parents don't pick up my call after being late to something, I assume the worse with everything. Now My mom is going to her hometown this week and it's rainy season where reptiles fear is more I feel I cannot take anymore anxiety and so I'm trying to seek help. Has anyone ever had this irrational fear of losing their parents. This post may help me cope. If you need any more info hit in the comments
