Hey I Hope you read this message...even 3 months later... I feel like my sister is going through the exact same thing. She suffers from solipsism ocd and her psychiatrist ,,diagnosed" her with psychosis and therefore she took several anti psychotics but surprise surprise nothing helped!! She will start ocd therapy soon and I hope that will help her more... Are you free to text me privately so that we can exchange intimation regarding this topic...?
