I was on Paxil once. Not a good thing.
Medication like these only mask the problem. You will still worry and your mind will go in a million directions, you just won't care as much.
Until you get to the root of your worries and fears, they will never be under control. Dr. Freud said that panic attacks were "Psychic awareness for danger". (Like you feel something bad is going to happen). Other doctors think panic attacks are linked to low blood sugar. My favorite minister says you need to change your stinkin thinkin.
I have experienced all of these in my life and have come to the conclusion that satan uses your fears to stop you from achieving God's plans for your life. Fear and worry stop you from going places. Places where you need to be..like canceling a job interview because you THINK you won't get it.
It's all about what you are thinking. "We" let our thoughts of fear control us instead of taking control of that fear and getting rid of it.
When these attacks come along, which are not everyday anymore, I just pray and tell God "I don't know what's going on or whoever needs protection but watch over whoever needs it". The attacks subside a few minutes, sometimes seconds later.
Good luck.
