Not to long ago some one else listed all there "what ifs". There are positive what ifs too. You can turn every one of the negative ones to positive. Hers were easier to turn around because she was just worried, you are determined to prove this right instead of wrong so it would be harder.
Not impossible.
Okay I see how you built this core belief. If your family has been telling you you are wrong and you have been proving them wrong (most of the time)( or at least in your mind) You have built a core belief that they are wrong. If you are right then this is a positive core belief, if you are wrong it is a negative. It doesn't matter, what does is you appear to have built one on it that says the doctor is wrong. A spill over from the first one. It seems to have spilt over and built other core beliefs about your other fears.
You could go get a second opinion or a third but with this strong of a core belief you are not going to accept their diagnosis either in which case it will just make the core stronger and you worse.
I won't lie to you, you are going to have to work very hard to bury this. First off can you get your family to quit arguing with you. That is just reinforcing your "what ifs" Giving them unwanted attention. The best way to get rid of something is to ignore it. It is important that they stop doing this. I know there is nothing wrong with you and so do you, but it is you that is going to have to prove it, not me or anyone else. I will help, and I will support but you have to do the work.
You have gone to a lot of trouble to prove you are right in your mind. Now you want to use that strength and determination to prove you are wrong starting with positive "what ifs". After you can accept that you might be wrong then and only then you get a second opinion to reinforce the new core belief that there is nothing wrong with you. Then and only then should you do exposure by looking at how rare this disease is and what the possibilities are that you could have it. Believe me when you get this far it will look a lot different.
Here for you,
