TTC paranoia?

Okay so I’ve just started TTC, but I have this awful paranoia that I’m not destined to be a mum and I can’t visualise myself pregnant and with a baby and it’s been like this for a while. I’m trying my best to put this to be back of my head as my bad mental illness (depression, anxiety, paranoia, BPD) but it’s hard.

My main question is has anyone else felt like this and gone on to have a baby? Am I just paranoid because I want it so badly?
