Mental Health Resource Recommendations

Hello; my name is Bradley (he/him/his), and I struggle with depression, anxiety, and self-harm. I am interested in understanding the experiences of other people who struggle with the same and different mental health conditions, and one of the ways I would like to express my story is by writing a piece of contemporary fiction featuring characters with various mental health conditions. My first steps in achieving this goal are to find information about mental health conditions, hear from people with lived experience, and portray these conditions in ways that are not stigmatizing or offensive. I'm wondering what articles, podcasts, videos, or books would effectively assist me with my writing? Feel free to let me know. Thanks!
