I suffer from it all. Panic, anxiety, sickness, labyrithitus, nausea, post traumatic stress disorder..
I would highly recommend not medicating yourself. Go to a doctor, it makes you feel os good to be understood and have someone tell you that everythig is ok, its normal, you are not going to die, you will get over it, and to keep constantly checking up on you each couple of months .. You will start to see your progress and that makes it easier to continue.
After 7 months I finally have stopped getting bad panic attacks, my anxiety is lower, my shakes have gone down, my chest still hurts and I get nauseous but the impending doom feeling has gone quite alot.
I take pills for my ear condition but nothing for anxiety.. I just try and keep occupied and accept the illness more than anything, just accept you have it.. Dont fight it, and then it will slowly fade away.
