My friend 20M has struggled for several years with magical thinking - which means that he connects unconnectable things together (for example he tells himself that if he doesn't pass his exam his dog will die or if he doesn't exercise his parents would get sick or etc.) I tried helping my friend by listening to him and we tried implementing sports activities and meetings with firends in his daily routine. However, everytime he gets to be alone for some time he starts to have these thoughts again. He has even been to a psychologist several times (some were doing CBT) but it did not help so now he doesnt want to visit any psychologist at all. These thoughts cause him to get isolated, depressed, suicidial, have mood swings and enormous fear of judgement. Now my question is: How can I help him to cope with these thoughts? I still think that CBT (cognitive behavioral therapy) might help him or do you maybe think that EMDR therapy is better? I know this might be a hard question but I am concerned and want him to be happy. 
I also have a suspicion that he might have an OCD. He is a medic and recently hhas done an autopsy and he is really affried that might have gotten prions which would eventually kill him and people around him

To everyone, I hope you are doing great and please stay safe. Thank you :)
