Yes I have some sadness for things that could have been better for me if I had known. I was born in the late 60s and was bullied at school, found it hard to relate to my extended family, and had few friends. Childhood was, relatively speaking, OK though - depression and anxiety didn't hit until I had to leave education and get a job & started raising a family. After my first marriage failed I went through several periods of depression alternating with anxiety and wanting to retire, then mid-life came along and I had a hard time making sense of it, felt suicidal on occasion and didn't know what to do with myself. I've only just emerged from that confusion, helped an awful lot by realising that I'm autistic and then getting that confirmed.
Thank you for your input. I dont know if I can go through formal diagnosis but a few doctors have said possible so I looked into it and pretty sure I am too
