Lots of love from others. Patience and understanding from others who understand it. Fresh air. Sunshine. Elimination of mental and emotional toxins such as violent movies or the news and negative people. Getting busy if you can. Sometimes there isn't anything natural and you will need to see a doctor for medication help-medications can help if you find the right one. Plus a little time to get through it.
But love and hugs really help, even if they are cyber hugs.
