Tasha - That definitely sounds like a panic attack. Those ARE really awful and I'm sorry you've been dealing with that. :(
I have several friends with that problem actually and the meds they've tried haven't done them any real good. At the best, it temporarily numbs them, at worst - it completely screws up their sleep schedule, hunger and hormones and makes them even MORE anxious!
It's not a quick solution, but I really must say, seeing a therapist makes a LOT more sense for a condition that is rooted in a lack of confidence than a pill to keep you from feeling at all. Yes, anxiety does have it's base in hormones and some people ARE physically more prone, and yes, some short-term relief can be good, but I think for the most part, it's a "learned" condition which develops over a long span of time and so, it's solution should be a long -term one as well.
Anxious people are anxious because they feel simultaneously that they are responsible for everything (including the hurtful words, actions and attitudes of others towards them) and that they are out of control (unable to change their situation). They allow others to place a value on them, rather than valuing themselves. They often become that way because too much responsibility and not enough affirmation was put on them growing up.
You need to learn that while you do have responsibility and the ability to change your life, you are NOT responsible for everything and everyone that is bad to you.You need to recognize and learn to avoid behaviors and thoughts that feed your negativity and anxiety, to understand that emotional states are not permanent and that the way you feel is not the way you have always felt or will always feel and will pass. You need to define what it is about you that makes you proud to be you and cultivate that.
It's so appealing to think that by simply taking a pill, all those problems can go away, but anxiety does not develop simply and unfortunately, it doesn't go away that simply either. What you need is to address the issues that are causing you panic attacks and anxiety. Like I said, I think a good therapist could be really helpful, but also good friends.
If you want to talk, I promise I won't judge you. :)
