Feeling Numb and Unmotivated

Idk how to feel, I feel numb, "emotionally blunt," I feel very low energy and unmotivated to do anything, I go to the gym six days a week and lately when I go there I notice myself doing less and less, idk, my Adderall doesn't seem to help, nor does the Exeffor I take, it's so hard to describe how I'm feeling, I don't feel normal, not like I don't feel myself, I just feel different, melancholy? Gloomy? Idk. Is it a result of my stress? Am I just... Not doing enough? It's been happening much more lately and I'm tired of it, I just don't feel right
