I'd also suggest try cutting out all caffeine and stimulants (if you take any). For me, the transition took several months and caused a bit of irritability, but getting through it changed my life. No more crashes, no more anxiety, no more headaches, and now I sleep easy.
- your sleep (how deep) and meal quality (how healthy)
- your sleep and meal patterns (what hours, how consistent)
- your personal hygiene (haircut, shaving, cutting of nails)
- your presence (punctuality, quality of clothing, how you dress)
- frequency of physical activity (sports, exercise, do you still get sunlight)
- frequency of you spending time with your family, friends, lovers, and pets
If nobody likes me because of that, then let them, i'm not a product that needs to match all the checkboxes
