I am having terrible health anxiety. Last week I ended up in the hospital because I was sure I had a blood clot in my leg and they ran some tests and said I was fine. Today I was sitting at work and felt a sharp pain in my upper ribcage under my left arm that lasted 2-3 seconds and went away it happened about 2 more times and I rubbed it and it hasn't happened again and then I had an anxiety attack. Started to wonder if it was a blood clot in my lungs about to kill me yesterday I had a pain in my neck but it has been better today almost gone. I started panicking about my breathing, could I breathe? I started making plans to go to the hospital. I get so frightened. This anxiety is taking over. Please somebody talk to me. I feel ok right now like I say the pain didn't last long. Thanks

Just to repeat something I said on another post, I agree nobody can self-diagnose a blood clot, but obviously it's just not true that there's always nothing wrong with people who are anxious.  But even if there was something wrong, those of us with anxiety overreact to it and make ourselves even more miserable.  Most people, including us before we had anxiety problems, took the good and the bad for what it was and didn't dwell on it.  We did what we had to do and moved on.  Anxious people get stuck.  You're stuck.  You need to unstick yourself, if you can.  Because your anxiety is progressing, I'd suggest a psychologist who specializes in anxiety treatment so you can stop this nonsense before it becomes chronic.

It is natural to have panic attacks when you think you are dying. However the doctors said there is nothing wrong. It is abnormal for a layman to think they have blood clots, so that is the problem to try to overcome.

You are living with fear, based on the faulty premise that something is wrong with your body. If you can accept the fact that you have no medical training and can't diagnose disease, then you will be able to accept that the doctor said you have no physical problem.
The first step is to stop Googling for disease, because you can find someone who died from any condition including a thumbtack injury that clotted that went to the brain of the victim. There is no comforting relief on Google, so the more you Google for disease, the worse you will feel as you locate other cases of unfortunate victims who had a 1 in 300,000,000 case of a freak calamity.
Next step is to reread what I wrote in the first paragraph until you either accept it, or else continue believing you know how to diagnose. If you can accept there is nothing wrong, then you will stop over-analyzing your body and ignore minor twitches, ouches etc just like you used to ignore them.  If you can't stop making up abnormal ideas that you are dying just because you get an ouch for 2 seconds, then therapy might be useful.
