I was like that after a major car accident i shattered 2 vertebrae in my neck and told i should have been dead or a quad, but ran a marathon 2 years later also i had a total memory loss of life before accident. What i did was looked at life as we know it.
What i can say is be yourself dont listen to others for advice to much as depending on others can become a job in itself. Take time to smell the roses, get a massage from a qualified therpaist who does remedial massage with myofacial release. It is an experience which will help clear your thoughts. I also took up tai chi and chi gunn.
They help clear the mind and go to a different level of life.
Take time out to smile at someone anyone each day, find a funny movie and watch it, give a friend a hug and smile, take a 5 minute walk daily. Go to a lake and feed the ducks.
But hey there are thousanRAB of poeple out there like yourself and dont look to hard for answers as to many questions cause stress on what to say how to say it and when
Make a plan that one day a week you will do something that makes you smile if you cant think of anything then laugh at how silly it is.
Hope this helps. Keep smiling and be happy,
