Please help - single mother in need of advice

Sorry for the long post but I wanted to give a full explanation if my ocd hell. It started at 13 with harm ocd , rituals , magical thinking . It then moved to pocd…. The last and current theme I have is making me feel really ill. I basically had a panic attack 11 years or so ago and a thought / sensation came into my mind ‘ I don’t feel like mea’ … this then extended to ‘ if I’m not me , who am I , who’s reality is this? Am I in a dream ‘ … I went into full panic mode with dp for months . Took myself to a and e to be told it was high level ocd and anxiety . Since then I have been on fluoxetine for 10 years but every 6 months or so this comes back. It’s now extended to me convincing myself I am in someone else’s dream trapped in a false reality … how the hell does this get reinforced by feelings? I feel like someone else !!! The brain is a crazy thing . I have a full time Hugh level job and a beautiful daughter but feel like I can’t relax because as soon as I do I get the panic thought/feeling ‘ I am ‘ a another ‘ I need to panic and address this paranormal episode I know deep down this isn’t real or right but it doesn’t stop the horrible sensations and questioning hitting me hard I have had cbt but not erp… if someone can relate or help I would really appreciate it ‘ a final note is I think this is all fuelled from being scared of psychosis and researching how a psychotic person wouldn’t question thee Ed thought but be adamant of false beliefs ‘ Urgh
