I don't know what to do. This is so hard to explain.  It's so much worse than what ppl realize.   I've been diagnosed with severe panic disorder at a psychotic level, OCD, Agoraphobia, PTSD and depression. I'm getting scared I'm going to stay in my mental state of derealization and panic and I'm not going to come back or everything is going to cause me to have physical symptoms of severe panic, fear,  feeling that I can't breathe, trembling,  loss of control,  dizziness, insomnia,  tingling in my face and legs  ect. 

I used to know my triggers and I would avoid them.  Caffeine,  certain medications ect. These past 2 years I have gone off the wall and I haven't been the same since. I have constant anxiety,  paranoia,  fear of when my next "panic attack" will be. 

I've been having issues with my lower back and I went to get an MRI. I've had those before.  For some reason it triggered an attack and I was holding on to the MRI tech crying hysterically begging her to take me to the hospital.  I had pain, heart palpitations and fast heart rate, fear, trembling, tingling in my face and arms,  couldn't breathe, loss complete control and I just wanted help. It took about 20 minutes to pass. 

Another ex.  I used to highlight my hair and ever since this started I didn't mess with it. I ended up trying to do it once and I had symptoms again of extreme paranoia and panic that  lasted for a few days. 

Certain smells trigger me now. I'm scared everything will become a trigger.  


Shit that I know that isn't suppose to hurt me is hurting me by causing whatever is happening to me to happen.  

Is it really a panic disorder or is it something worse. 

I've gotten an MRI of the brain 2 years ago it was normal.  I'm having issues with my back so far degenerative disc disease, radiculopathy, ect. 

Was suppose to get the MRI I guess to see how bad it is or if there is anything concerning.  
Now I can't do MRIs, I can't eat the same things, I'm just not the same person.  I'm scared I'm going to get into a state of psychosis and not come back.  

I'm scared of all the psych meds. I take ativan to calm me down but I'm literally terrified of pills. I  tried Neurostar and again triggered my episodes. 
I'm still convinced an underlying health issue is causing this.  Drs don't believe a person can be this sensitive to things.  I've been tested for everything except for my back.  

What is happening to me? 
Any advice would be appreciated.
