how long does it usual take for someone not to be very very sad about a family member that passed away

That depends upon too many variables to give a definite answer.

It varies, and what you mean by "very sad". If this someone is you, I suggest you seek out professional assistance. You can start with a school counselor, or even a trusted wise adult you know, and they will hook you up with an appropriate professional. My long term wife died 10 years ago, and I still suffer loss of her in my life. I find things to keep me busy, and productive, and helping others helps me cope with the loss.

thank you

Coping with the loss of a family member is a complex and personal process that can vary greatly from person to person. Grief is a natural response to loss and there is no specific timeline for when someone will stop feeling very sad. However, over time, most individuals find ways to adjust to the loss and their level of sadness generally lessens.

If you or someone you know is experiencing grief, it is important to allow yourself or them to grieve and feel the emotions. It is important to remember that everyone's grieving process is unique and there is no "correct" way to grieve. Here are a few general suggestions that may help someone through the grieving process:

1. Allow yourself to feel: Acknowledge and accept your feelings of sadness, anger, guilt, or any other emotions that arise. It's normal to experience a range of emotions during the grieving process.

2. Seek support: Surround yourself with supportive family members, friends, or seek professional help like therapists or grief counselors. Sharing your thoughts and emotions with others who understand can provide comfort and solace.

3. Take care of yourself: Engage in self-care activities that promote physical and emotional well-being. This can include maintaining a healthy lifestyle, getting enough sleep, eating nutritious food, and engaging in activities that bring you joy.

4. Honor your loved one: Find ways to remember and honor the person who passed away, such as creating a memorial, writing a letter, participating in a tribute, or engaging in activities that hold significance to them.

Remember that healing from grief takes time and there is no set duration for the sadness to diminish completely. If the grief becomes overwhelming or shows no signs of improvement over an extended period, it may be beneficial to seek professional help.
