Question about the app and my mental health

So this is just a question about the app and kind of for me. So I'm not officially diagnosed with anything but there's things I'm pretty sure I have or I at least want to talk about them to see if other people feel the same way or have the same symptoms, I want to hear from other people but when I look up what it is it tells me to put the year I was diagnosed but like I said I haven't been so idk if I should just put when i started feeling or realizing my symptoms or I shouldn't put it in at all. when I put in social anxiety it told me to put the year I got diagnosed or when I started feeling that way and I said the year I was born because I've always had social anxiety, social anxiety I'm 99.9% sure I have and the app said to put the year I started noticing it but other stuff says to put the year when I was diagnosed
