when i had a panic attack i felt dizzy and was difficult to breathe and felt like i just wanted to get away and after i couldnt stop shaking. apparently i had a fast pulse aswell.

it's might be a panic attack, you should talk about what makes you cry and stuff...you can private message me if you want...also, try some relaxation techniques..they do help...

it's probably anxiety.
has anything drastic happened in your life recently?
