hello, Bloomajs, welcome to PC.
i found a little-known type of sound therapy that helps the brain rebalance itself, and even regrow neural connections so it can function better. i don't know if you've heard of Binaural Beat Therapy, but it can be a permanent healing solution for some. it took me seven years of daily listening to 'recover' from bipolar and five other diagnoses, including OCD and Anxiety.
you can google the term and find many good sound tracks on Utube, just be sure you listen with stereo earphones. the therapeutic model i used i bought from a company called CenterPointe.com. they sell in 6 month increments if you need that, or you can just buy into the 'Forever' program. what is important is to listen, as directed, every day (for a half hour or an hour, depending on which section you are on).
the sounds are different for each ear, which causes the brain to be stimulated to rebalance itself, kind of like EMDR, and the effects are, or can be, permanent. i hope you find something which will help you live without the feeling of imminent death and desperation, which i knew so well.
best wishes~
