How can i control my crying over losing my only sibling who was everything to me ?

Loss: I am very sorry to hear of the loss of your sibling. I have had the same experience and i know first hand how devastating it can be. Share your feelings with those close to you, this kind of loss is too much to cope with alone. Consulting with a mental health professional could also help you considerably. Take good care.

Therapy: I am sorry for your loss. Grief can be a painful burden and it often helps to speak to someone who can guide you through the stages. It sounds as if you two were very close. I am sure your sibling wouldn't want you to grieve too long and hard - would want you to move forward in life and be happy. Try celebrating the good memories and remember the love you two shared.
