You know, the first time I went to therapy. I was petrified. So anxious, so nervous and the funny thing is; I wasn't the client! I was the therapist. Felt a bit stupid after, considering how each person feels, but soon as they walk in the door and the conversation starts; you'll forget all about it as your attention will shift to more important issues.
Medication is a temporary measure ONLY and should only be used until you can learn to live without (and you will), if you're feeling panicky here a few things you can do:
1 - This is old school, but you will find in any meditative scripture or any discipline that focus's on peace; breathing is the key. Simple works best, always. Counting backwards from 10, breathe in. Each time you count down, make the time between counting from one number to the next slower. Try match you're breathing against the numbers, so you should end up breathing in and releasing slower every time (don't hold your breathe).
2 - This sounds a little odd, but there is method in the madness here. If you're able too; stand on one foot and focus on an object at the other side of the room that's at eye level. Do this for as long as you possibly can. Why does this work? By standing on foot and fixating your gaze you are conciously directing your cognitive functioning (thinking side) to the object you're focused on whilst trying to maintain your balance/posture. You're brain only has so much 'room' to process thoughts and feelings. Try it!
3 - List off 10 different things. Could be 10 types of cars, 10 different ways to make pancakes, 10 ways to excercise, whatever you want.
4 - If possible; sit down on a seat that fully supports your body from head to toe. Lying down works equally well. Starting from the muscles in your foot, all the way to your neck, slowly tense those muscles and then release after several seconds. I generally start with my toes (curl them up hard as I can, release) then my foot, calf muscles, legs, thighs, working all my way to my hands and up to my neck. It's advisable that you don't tense your neck, instead loosen it up, let your head bob gently side to side. By the time you've done this, not only have you relaxed every muscle in your entire body, but hopefuly you're thinking has shifted too.
5 - Feeling agitated? Pacing the room? Can't sit still? Again, sit yourself down and stop. Stop for a few seconds and then flip your hands over so the palm of your hands is facing towards the cealing and your hands are resting comfortable on your lap. This works because, by opening your hands; you're essentially disengaging you're flight/fight mode.
These are all distractions, it's important to look deep down, yes, but it's also important to give yourself a break.
