recently diagnosed late in life and looking for support to understand

Hi, I have recently been diagnosed with having autism, quite late in life, and tried to find guidance with trying to understand myself, may past, my behaviours, my difficulties/challenges in life. I'm finding this difficult. If anyone has any links I can look into that will help me here, this would be great. I have had a few weeks off work, trying to understand my diagnosis, who I am, feel confused due to masking heavily most my life, do I mask (which has had a negative impact on my mental health), or do I mot mask. Thinking about it is overwhelming. I live on my own, with no friends to share my worries with. So thank you for reading, it helps me feel I am not alone.
