Think and share
I have been suffering from the
bad habit of overeating for decades. Every time I feel upset, I eat a lot. Overeating is the most effective way for me to relieve stress temporarily. It is ironic that I eat even more when I feel anxious about gaining weight. I am overweight and frequently have a stomachache. What shall I do I really want
to get rid of this terrible habit.
My friends call me a night owl.
I often stay up late and go to bed after 2 a.m. When I am actually in bed, I still can't help playing with my cellphone for one hour or more. In other words, I fall asleep later than 3 a.m. I feel dizzy from time to time. I find it hard to work efficiently at daytime. Sleeping late even makes my skin look bad. I know it is an unhealthy habit but I don't know what to do.
