You are valuable and valued! Of course, I only know you from a distance, through your writing. But over the relatively short time I've been getting to know you, I've come to understand what a remarkable human being you are.
The world needs more wonderful people like you to spread love and acceptance.
You matter, and I for one would miss you deeply if you left.
I don't know if the pain of losing a parent diminishes as we age. It might. When I lost my father 4 years ago, I grieved deeply, but I'd had years to prepare for it, and it was time for him to go. He knew it and wanted it, himself. His body betrayed him every minute of every day, and he just didn't want that anymore.
So at least a small part of me could be happy that his passing was peaceful and pain-free.
I don't know about your mother's circumstances, but I can feel your pain, and I am deeply sorry.
Please go to the doctor and find out what's wrong. I've been having symptoms this spring and summer, and I waited until it was almost too late. I'm lucky to be alive today and able to expect many more years of life.
Don't make the mistake I made. Please.
