I just need to know I’m not crazy

I’m 18f, and I’m pretty sure I have BPD I was diagnosed with traits (I could only be diagnosed with traits as I was waiting for an ASD and ADHD diagnosis, which I received). But now I’ve got them I can go for the full diagnosis. The thing is people are saying not to, they are saying that this diagnosis will make life harder. But I just want to know I’m not crazy and that I’m normal to some people and that what I feel is something that others feel too (to an extent).

Im on the list to receive the full diagnosis but should I remove myself? will it make life harder for me knowing for sure and having a label? Has it stopped any of you from doing anything you want ti do?
