hello everyone. i'm 24 years old and i recently started having panic attacks. is it normal to feel the symptoms for 2 hours? like not being able to breathe, chest pains and light headedness. i thought they lasted about 30 minutes. i'm sorry for sounding stupid, but like i said i just started experiencing attacks 3 months ago so i'm a bit confused with all of this and honestly i'm very afraid because i try to calm myself down and i just can't seem to.
