BPD, ASD and recurrent illness

I am 27 and I have received two undisclosed diagnoses that I found through requesting my medical records: BPD at 24, and PDD-NOS at 9. Is PDD-NOS still an applicable diagnosis in 2024? Is it different to AS? Is BPD and ASD alongside recurrent illness common...? It feels like I have been dealt a bad, if not the worst hand.
