Hello there, please forgive me to enter in your prívate space but You should do what You said about keeping busy Even helping others. The feeling You have Will go away if your Mind Is busy and You don't have time to think or go over your past thoughts. With the time your brain Will do it automatically so You Will feel less bored and more Open to life. Learn New things , visit people, help others , practice any kind of sports but keep yourself busy until your brain Is in track.
