Panic attack, heart disorder, anxiety?

I get palpitations ALOT. I once got them when I was riding my horse and it slipped so I got real scared and got them. Another time that it happend relating to fear or anxiety was when I was talking to my friend whom I am real shy around and got them. I also sometimes get them in dreams. But most of the time they are mainly out of nowhere.
My face gets hot, my body starts shaking and I feel dizy every once in a while but never faint. My heart beat irregularly and skips and sometimes even feels like it stops. I feel like **** when it happens, and I live in fear each and every day of getting them. I am so scared next week at highschool rodeo i'll get them while i'm doing my event.
I HAVE gone to the doctor three times before--with all three being different doctors but they never found ANYTHING. It makes me so frustrated that they don't even give me a clue on what I have and just stare at me like i'm some dumbass teenager.
I'm tired of living in fear each and every day, I want to know whats wrong and what I can do. I have a friend I talk to alot, a best friend. I take vitamins everyday and a gaba suppliment--which now I guess is just a fakeout. I drink alot of water, I eat when I can. I have lost alot of weight. My iron level is fine.

I think you actually need some treatment for your anxiety as its at a level that interferes with you living a normal happy life.
You have what I would call a serious case of anxiety attacks. Go back and see the doctor again...take your mum too and dont give up until you get some help...you may need some type of medication to help calm and relax you as you learn to deal with the stresses and issues of life...its OK...its pretty fixable...you are just more sensitive than others so are having a harder time dealing with things.

You are not a dumb teenager...and your anxiety is a real diagnosis and problem that needs to be treated. Keep trying until you find a sympathetic doctor...I wish you good luck...

If the local doctors clinic has several doctors, call them and ask if any of the doctors there have a special interest in anxiety and teenagers...

and speak with your mum too...she will likely want to help and support you.

Hello, Um wow your problem sounds just as what I do. See 2 years ago when I was in 5th grade I passed out in the middle of the hall way. I went to the hospital and they said I was just dehydrated and I thought that was just not right. And well I drank TONS of water and I passed out in my house and they still said I was. And well I figured out today. See I already new I had a little hole in my heart. But I never thought this could have been the resin why. The resin why I had all thos feelings was cause the little hole in my heart. I have a Q on here thats about it. And I have to have Heart surgery soon. I'm kinda scared tho. I'm only 12...

Hey, after I read this it sounded just like the problems i dealt with for awhile, until I hit 22 recently. I used to get hot, dizzy, exhausted, and all I could ever think about was my chest hurting. Am I going to die? and why won't anyone help me! My chest doesn't feel right! I went to the doctors and emergency room all that stuff, and they told me I had "Heartburn" to I had "Arthritis in my joints". I didn't believe it. But I wanted to share my wisdom on what I did and what I noticed. First off, I noticed that all I did was obsess about my chest pain. I was so scared and all I ever did was worry if I was having a heart attack. This led to anxiety and panic attacks. So now all I worried about was this anxiety, and finally I felt the dizziness and burning up. Then I thought oh man this is the end, I have something wrong because I am getting dizzy. Looking back at all of it now, I can tell you that anxiety was the cause of ALL of it. I started taking antidepressants, and over time I just stopped obsessing about it, and then finally I hardly ever think about it. And my chest only hurts WHEN I THINK ABOUT IT. I realize now that I was getting so anxious I was making myself dizzy, or nauseous which further made me sicker. But I remember how tough of a time I had with all of it.. It sucked! So my advice to you is you HAVE to tell yourself that you are fine! 3 doctors told you so. You are young, and not fat, so why would it be your heart??? If you think you might feel anxious then I would be getting to the doctors office to get antidepressants. Anyway, If this sounded similar to your problem then I hope i helped. kgray35@yahoo.com is my email if you want to talk further or need someone who understands. Anywho, good Luck!
