If your self-confidence is connected with approval from others, you may be in a cycle of dependence, and too much dependence on the reactions of others can lead to frustration. Of course there is a fine line here, but err on the side of healthy self-esteem! Treating yourself well is the way to do this. Be vigilant about getting your exercise, eating healthy and delicious foods, and above all, getting your rest. If you have trouble sleeping, brew chamomile tea to help relax at bedtime.
