I've name changed.
I've had anxiety for as long as I can remember.
Around 2017, I was due to have an operation and I remember this triggering what is now a long term problematic issue that I just can't seem to get rid of, and I'm desperate.
It basically started with muscle tightening, which turned into pain around my shoulder/chest/back/arm and then I got nerve issues in my fingers and shoulder.
I was convinced I somehow had breast cancer as I was getting very odd hot sensations in my breast.
To cut a long story short, I had multiple MRI's and breast checks and there was nothing wrong, it was all me. I was tensing my body so hard it was creating all of this. It took over a year to learn not to do it and I was so happy when it finally went.
Fast forward to two years ago, I moved house, the house had mold, I was allergic. I changed the way I was breathing and holding myself and again this created a really unpleasant set of symptoms that I still suffer with to this day.
I became ill with a respiratory problem and developed some weird phlegmy throat and cough which I was told was silent reflux.
Took the medication, it seemed to help but it never went away.
Basically I realised that it was all me again. except this time I can't make it go away and I'm desperate because the symptoms are so unpleasant they affect my day to day living and today I woke up and thought I just want to die.
I don't want to drip feed so I will list my symptoms I currently feel everyday:
Tightness in my throat
The need to cough and clear throat
Tightening my stomach (literally doing it now)
Breathing fast and shallow which creates burning in my mouth
I have taken PPI's, gaviscon for so long and they do nothing. I know this is not reflux. I had an X-ray of my lungs, they're absolutely fine.
When I do things that distract me, my symptoms go away or they're lessened. This is my anxiety isn't it? Something is mentally wrong with me and I just don't know what to do about it.
SSRI's don't agree with me. I take amitriptyline but it only takes the edge off. Propanolol does nothing for me anymore.
I just feel like I'm beyond being saved anymore 
I'm so sorry that was such a long read.
