Advice. Please, Anyone, This Is Getting Ridiculous.

About three weeks ago, I went to the doctor because I was having trouble breathing and chest and arm pain. He, just by listening to me speak, without bothering to listen to my heart or anything, prescribed me with having anxiety. He put me on welbutrin and xanax (as needed). The chest pains have decreased, but i'm still having trouble breathing and i've gotten some new, slightly frightening symptoms as well.

The other night my whole chest area up to my face went numb and then tingly. Sometimes just one of my arms gets numb and lately, my there's been a numbness around my right eye. I've also been getting sharp pains in the back of my head that don't last very long, but they're annoying. I feel like I can't get enough air in my lungs, sometimes even yawning and taking deep breaths doesn't help. The chest pain has come back today, and for the past four days i've had to take xanax just so I could sleep.

My family keeps assuring me that it's just anxiety or that i'm crazy and they won't take me to the er or set up a doctor's appointment again because we don't have enough money for tetst. This is driving me crazy, I want to believe it's anxiety but there's a nagging feeling telling me otherwise. I can barely do anything I used to do anymore and it's really starting to make me wish I would just die so I wouldn't have to go through this !**@! anymore and stop driving myself and everyone around me crazy.

So... Advice? Anything? Please, help me.
