  Thank you ..I hope I will find ways but worrying about my child and husband will be also stressful no ?:)))
context: What you are describing is called "existential dread". It is very common. Many people go through an existential crisis at one point in their life. 
  Ultimately you got the right answer already. You need mental health assistance. 
  What worked for me was getting married and having a child. Now that I have others to worry about I don't think that much about my own death. There may be a different solution for you. Usually there is a solution for everyone. It's an extremely common malady.
