Something weird I noticed about myself o.O

[Subsonic_Noise]

Well, I have no clue how this works and why, but I noticed the following about myself:
I don't trust me.
At first this sounds silly.. and probably still is. But, let's take the following example. I have had heart problems for a while, and they get pretty bad from time to time, with the heart beating unnaturally fast, and me feeling like I don't get enough oxigen to an extend that I can barely stand up, my vision fades to black, etc.
Thing is, I don't believe it. I think I am just imagining all of it, and that makes absolutely no sense. This isn't the only thing either.
Anyone have a clue what this is?

No o.o
But have you seen a doctor about it? I suggest you do asap...

[Subsonic_Noise]

Well, obviously so far I haven't. I think today might actually be the first time I even admit it is real to myself. That has kinda kept me from going to see one.

[Fantasist]

See a doctor asap, Sub!

I will try to get an assignment I guess. I had this for quite a while though, it's probably not killing me, but annoying. Thanks for caring tough.

Of course
And things like this are a matter of safety. You shouldn't even have any doubts remaining.

Just a (very bad)guess: abnormal thyroid?

I have no clue. My family has a history with heart problems though, my brother even was born with "half a heart", meaning one half of the heart was degenerated and barely worked. He died of that before he was one month old.

Might be heart palpatations.
My aunt used to have them (before dying of a heart attack), and she described them very similar to you do, except she didn't have the doubt that she was imaging it...

Either way, it would definitely be wise to get that looked at by a professional.

Ah, I'm sorry to hear that. :/
