I have starve myself when I’m under high stress
You wrote that you starve yourself when under high stress. Do you mean that when you are very stressed you don't feel hungry and therefore you don't think about eating or do you mean that when very stressed you purposefully don't eat, feeling better for the very fact that you are not eating for many hours?
It would be helpful to have more information. If not eating is effecting your health, then you probably should do something about this. If you're not eating just so you can get through something and eat when it's over, I think that's okay. I do that sometimes, myself. It's important to take care of our bodies - give them proper nutrition, rest, exercise, etc. Let me know if I can help you more!
