I feel you, happens to me all the time :(
they just mention it is all in the mind I hate going to the hospital and they just tell me that
Hello,
Some of this could be anxiety related, but, also it could be from a condition called "Costochondritis" (inflammation of the ribs) I have that, and I have some of the symptoms that you mentioned. The two together can certainly cause issues you are having.
I would like to suggest a visit to a chiropractor, many can help with the Costochondritis with a simple adjustment.
As to the anxiety, it is hard at times to control, try taking nice walks (weather permitting), and doing things you enjoy to get your mind off of it, I know it is difficult, I too, have anxiety, and some days it is awful, others, I am OK.
That's sad. It feels very bad, i go through this often. I hate visiting hospital even hearing the crap from doctor makes me demotivated.
