I'm 15 years old & a few years ago i started having spells of anxiety, nervousness & depression, this was just as i started high school. it went away for a long time, but recently I've started having a lot of anxiety, light headedness, tension in my throat, crying spells, paranoia, nervousness, confusion, slight forgetfulness, stress and a racing heart very often, I've got hardly any self-confidence and i often feel stupid or delusional, like my mind is clouded. in class I've had a strange panic attack sort of thing, but it would only last a second and its only happened once or twice. This really scares me and i would like to do something about it.
