Do what your heart says. If you want to talk to someone.. please talk. And if you don't wanna talk.. then take your time. Involve yourself in the hobbies or the activities you enjoy. Do excercise, go for long walks.. excercising release happy hormones n it makes you feel good.
And... Please do consult a doctor as they are the experts. We can only advice you, but the doctor can heal you.
Take care. Khyaal rakho aur Khush raho.
