Talk to Psychiatry on OCD Disorder, And Flouxetine

i was taking flouxetine 40 mg for OCD . after 2 months of taking flouxetine my ocd got better upto 75 percent. so for another 2 months my ocd was 75 percent better but after that me and my psychiatrist thought we should increase it to 60 mg. after being on 60 mg for 2 days one of our relative died. and we went to their house for taziyat.before this I was having no obsessions but only 1 obsession started related to our relative death and i had those thoughts for 2 weeks and my ocd started getting worse day by day and after 1 month of all this my ocd got worse like before and we thought if flouxetine have stopped working and we decided to stopped flouxetine.and we stopped it. i want to know if my ocd got worse due to dose increase or flouxetine stopped working or due to the our relative death which caused some obsessions and after this ( flouxetine ) we tried alot of other ssri and antipsychotics but none of them are working. what should i do know. should i retry flouxe
