I think that "personalisation" as well as "mind-reading" (just "knowing",with no evidence, what another person may be thinking about you) are quite common in people who live with Major Depressive Disorder - they sure were for me.

It might help if you saw a clinical psychologist who has experience of using Cognitive Behavioural Therapy with his/her clients. Essentially CBT entails learning how to notice what are called "Negative Automatic Thoughts" (NATs) - like personalisation and mind-reading - and then challenging them - asking "Is there any evidence for the validity of that NAT?" - almost always the answer is "No" and that can be empowering.

Learning how to use CBT methods, with help from my clinical psychologist, made a big difference to my recovery from Major Depressive Disorder - I recommend them.
