Can it go away?

i’m a 16 year old female. I’ve had crazyyyyy health anxiety since the begging of this year. recently i’ve felt stuff in my chest and symptoms keep getting worse. But also the anxiety is getting worse too so i can’t tell if my anxiety is making these symptoms and it’s actually nothing or they are actually something. i’ve been crying and stressing tremendously about these symptoms and ive even tried calming mechanisms that my therapist has given me and nothing works. i do google a lot and ofc it shows my symptoms leading to bad things so i’ve tried to stay away from google but not knowing what my symptoms mean is worse. Im basically spiraling at this point and need to know if there’s any other ways of calming or if my symptoms are real and im not actually crazy.
