Wild Anxiety attacks

I don't really know how I feel, yesterday I had an anxiety attack that lasted more than 2 hours,
*I felt my head very heavy was very irritable,
*I was finding really hard to spell in my own language ( not english if you haven't noticed)
*I just wanted to stop the pain.
*I had to yell just to focus in something else, I think when you have to yell is 'cause you don't really have any cope mechanisim left to try.
*For more than 7 months , the pain was so, that I had suicidal thoughts.


Anyway today is a better day for me but still feeling bad but I don't know how exactly.

Do you have any activities that proved to be true on yourself that you would share with me?
