Explanation:

Answer:    Blood is needed to keep us alive. It brings oxygen and nutrients to all the parts of the body so they can keep working.

how do you get over a loss of a loved one ?

Answers

Answer:

you dont you will always be affected by it no matter what you do

Explanation:

Answer:

Visist Jw.org,  Below is an article i found on this website. Hope it helps:)

Explanation:

“I felt helpless when my older brother died unexpectedly. Months later I would suddenly remember him and feel sick, as if a knife were stabbing me deep inside. At times, I was also angry. Why did my brother have to die? And I felt guilty for not having spent more time with him.”​—Vanessa, Australia.

IF YOU have lost someone you love in death, you too may have felt a wide range of emotions, from sorrow to loneliness and helplessness. Perhaps you have also felt anger, guilt, and fear. You may have even wondered whether life is still worth living.

Be assured that grief is not a sign of weakness. It indicates how much your loved one meant to you. However, is it possible to find a measure of relief from your painful grief?

HOW SOME HAVE COPED

While your pain can seem unending, you may find the following suggestions consoling:

ALLOW YOURSELF TIME TO GRIEVE

Not everyone grieves in the same way or for the same amount of time. Still, crying can provide an outlet for fragile emotions. Vanessa, quoted earlier, says: “I would just cry; I needed to release the pain.” Sofía, whose sister died suddenly, says: “Confronting my thoughts and feelings is very painful, like opening and cleaning an infected wound. The pain is almost unbearable, but it allows the wound to heal.”

TALK ABOUT YOUR THOUGHTS AND FEELINGS

Understandably, at times you may wish to be alone. But grief is a heavy burden to carry by yourself.  Seventeen-year-old Jared, who lost his father, recalls: “I talked about my emotions with others. I doubt I made much sense, but it was good just to be able to express myself.” Janice, quoted in the opening article, adds another benefit: “Talking with others was tremendously comforting. I felt understood, and I didn’t feel so alone.”

ACCEPT HELP

One doctor says: “The bereaved who allow friends and relatives to help them through [the] initial period [of shock] tend to continue to move with some ease through the different phases of grief.” Let your friends know what they can do to help; they likely want to but might not know how.​—Proverbs 17:17.

DRAW CLOSER TO GOD

Tina says: “When I suddenly lost my husband to cancer, I could no longer confide in him, so I would tell God everything! I started each day asking him to help me get through the day. God helped me in more ways than I can mention.” Tarsha, who was 22 years old when her mother died, says: “Bible reading was my daily source of comfort. It gave me something encouraging to think about.”

VISUALIZE THE RESURRECTION

Tina continues: “Initially, the resurrection hope didn’t comfort me because I needed my husband​—and my boys needed their father—​right then. However, now, four years later, I cling to this hope. It’s a lifeline for me. I imagine seeing him again, and it brings me such peace and joy!”

You are not likely to experience instant relief from your grief. Nevertheless, Vanessa’s experience can be reassuring. She says, “You think you’ll never get through it, but you will see brighter days.”

Remember, while the void you feel in your heart may not disappear, life is still worth living. With God’s tender help, you can still enjoy warm friendships and a purposeful life. And soon God will resurrect the dead. He wants you to be able to embrace your loved one again. Then that pain in your heart will be healed forever!

Bible Verses That Can Help

God cares about your grief and tears.

One Bible writer said to God: “Do collect my tears in your skin bottle. Are they not recorded in your book?”​—Psalm 56:8.

You can pour out your heart to God.

“Before [God] I tell about my distress . . . I call to you, O Jehovah, * for help.”​—Psalm 142:2, 5.

You can have hope.

“There is going to be a resurrection.”​—Acts 24:15.

God promises to bring back to life countless people who have died, and he yearns to do so. *​—Job 14:14, 15, footnote.
