I'm very familiar with morning anxiety at that's the time I'm most prone to panic attacks. But mine were work related when I was working. Had to go on extra meds to control it. Now I'm not working for the last three weeks I'm finding my anxiety getting worse late afternoon to evening. I've got a lot going on right now that I'm trying to unpack. I found a strict routine in the morning helped when I was going through the phase. It bought a sense of consistency.
