i used to get panic attacks, they go when u get your head around them. When i had them my heart felt weak and i got palpitations and all i could think of is, im going to die or something, eventually i knew when the attack was coming and could calm myself down before it started by telling myself its just a panic attack. i read a book that cured my mum and brother too, i'll try and find out the name of it if u want, its a brillient book.
