honestly any personal experiences/tips anyone has are greatly appreciated. 

for example, recently my anxiety has been at an all time high. we just rescued a kitten from my dads car and i kept worrying something was wrong with him even though the vet said everything was fine. then my older cat had what we assume was a stuck hairball in his stomach that eventually cleared but now i feel like i’m reading too much into all his behaviors that were once normal and now freak me out. my new job is also taking advantage of me with hours when i just want to be home with my cat.

it feels like i have a heavy ball in my stomach and i feel sick all the time. my cat gagged today and it caused me to almost have a panic attack and there is literally nothing wrong with him. 

any advice on how to calm down or handle this kind of stuff?
