Hello everyone,

I'm sure some of you have the pleasure of having a psychosomatical disorder. 
For my part, I have to deal with nausea for 9 years now. During that time it has been getting better and worse. Like some time I'm not feeling sick at all to constantly feeling like I'm about to throw up and not being able to eat. 
I'm feeling extremely nauseated lately, especially at night when I'm trying to fall asleep, and I just want to cry and cut myself. 
How do you cope with something like that? I'm hopeless at this point because none of my techniques to calm myself would help. 
My techniques include:
- controlled breathing 
- sensual distraction like cold water
- other distractions like reading 
- stroking my stomach
- talking positively to myself like saying that I won't throw up 
- picturing the sickness as an object that I'm imagining to wander downwards my body so my stomach isn't as pressured 

I'm very thankful for any reply and I'm sorry for any grammatical mistakes.
Have a lovely day/night. :)
