You can't depend on your mother to be your sole source of comfort and support. It's too much for her. She's done it all your life. She deserves a life of her own now.
You seem very needy and blaming. You're not getting your own way and you're angry. It sounds like you wear people down with all your energy instead of using it to improve yourself.
Try focusing on yourself and doing things that help you in your life. Don't blame or shame other people and don't make excuses. Try that for a month and you will see a major improvement.
