It sounds like you are in a toxic environment. And if I am honest, I glean an overdependence on your part on your mother and also on your parents' providing you with a roof over your head.

It's time for you to find a way to wean yourself from this dependence on your mother and to establish some other interests and relationships. I agree with the others that you should move out and learn how to live on your own. Maybe then, by developing more self-sufficience, your relationship with your parents can improve. They may be overwhelmed by being your sole source of everything in life (in addition to their own personal issues).

I hope this does not sound too harsh. Please see a therapist and start to explore how you can focus more on enhancing YOUR life (not theirs) to be more fulfilling. I am wishing you all the best.
