i've had the exact same trouble for the past 3 months.
but i've just recently seeked help.
if you go to your doctor
they could recommend perscription pills such as Beta Blockers which i am taking.
i also had a panic attack
i haven't had one quite the same since.
yet i'm having the breathing trouble problem and don't like to be left in alone.
my doctor has recommended me to a psychiatrist
so i can maybe find a cause.
so maybe this could work for you because they also teach you breathing exercises which should calm you in such a situation
i know you must feel down, i'm only 16 and used to be really sociable
but not i just wanna stay in
but i'm just trying to say to myself, i'm okay and the body breathes by itself, so nothing serious can happen.
you will be okay if you seek the right help before it takes over
i hope this helps and i really hope everything works out.
i know how bad things seem.
