Struggling with those symptoms

Struggling with those symptoms

Need help identifying stuff

I'm undiagnosed probably don't belong here but i experienced stuff that seems eerie to me. I work as a photographer there are shots and maybe even shoots i don't remember being there but not to the extreme i do know that they belong to me. And shots i look at them that actually it feels like someone else took them. Generally i had been going through periods of derealization. And i do have paranoid ideation i used to accuse my ex of cheating putting stuff in my coffee/ ideas of reference. Everything is mild though. I do function normally though it doesn't get in the way of anything but maybe once or twice weird incident happened like someone asked me if i had a brother it took me like a whole minute to answer which i don't i only have sisters. But it comes and goes sometimes i remember being there and remember the whole events.
