My gut instinct is that your mother may be wanting something else but doesn’t know how to put it into words. Not to say that she right, but I can definitely relate to that emotion.
Speaking as a person who is close to someone who is depressed, there is a sort of mental drain and negativity-by-diffusion associated with being near someone who is depressed, and it’s really difficult to put into words. I can know full well that depression is a clinical illness and that the other person can’t help it, but I will still get frustrated over their inability to match my energy.
If your depression and anxiety are as limiting as you say they are, it may be a good idea to talk to a therapist and get some medicine for that. Speaking from my own observations, you can definitely fight depression, but only to a small extent. Severe depression and anxiety are debilitating to the point where you will need medicine just to get close to what a regular person might feel
