Well, you're NOT alone because here we know exactly how that feels. I sure as hell do. Zero energy is all too familiar for me. Like you, I try to push myself to walk and usually feel better when I do, but I tend to walk where no one is around to see me. Those times like yours when meds aren't working or haven't kicked in yet can be the worst. There definitely are people who can help. If you're not talking to a therapist, counselor or equivalent, then please look into that, hard as it might be. It has made a huge difference in my life and I have often felt JUST LIKE YOU ARE FEELING NOW. You're worth it, keep on working on it and it will get better. Peace... Alex.
