There will be those who are positive, uplifting and supportive. Those who are negative we will talk about later. Maintain substantial and consistent contact with friends who give you positive energy. Meet for breakfast or lunch. If they are long distance, consider your phone bill as a mental health expense.
Life is an exchange of energy.
Select those people with whom you have an equal exchange of energy. You can't afford to spend time with those who drain your energy. Create your own support network of those who understand and are encouraging of your efforts. Nurture your spiritual side. Whether your belief system is a formalized religion, or a more amorphous form, embrace it.
