https://www.amazon.com/Its-That-Youre-Not-Understand-ebook/dp/B073XXYKLP I'm re-reading this right now! Sorry you lost your mother, I lost mine 9 years ago and it still feels crazy.
I was 21 when my mom died to suicide. I was really depressed for a few years, just feeling intense sadness and hopelessness. It's been up and down since then, going through a rough patch right now. I'm 30 years old but I still feel abandoned and just have trouble accepting she took her own life. Therapy, friends, medication, exercise, distractions, art all help. I'm currently re-reading It's OK That Youre not OK. I'm really sorry you lost your mom at a young age, it's a pain that the average person just doesn't get.
