I think your mom needs to learn or brush up on energy waste no, really. Giving such energy to another is very tiring, but she also might be allowing just any one to "steal" her energy if she is too open. I believe God gives us all we need for ourselves and to share for those in need. Maybe she needs to go back to the Source more often to maintain a living level of energy?
Perhaps you can with time learn to share your energy with her, and vice versa, as a starting point. Mindfulness does help to limit wasteful energy spending imo. Learning how to block an energy sucker is an important skill... you'll know who they are if you try to help (even here on the web) and give and give and give and they never progress---they just suck the energy out of people and go on.

Seven minutes a day. That's all that is required of the brain to clear and clarify what it is you want... no distractions etc... IF you worship and praise God that amount of time, (if that's Who you Believe in) then your benefits are compounded.
