Show of Hands

It’s time to look within yourself.

God is always close at hand, just a prayer away. One must expect tragedy and suffering in this life, in this fallen world, to not expect it is unrealistic.

Some good advice given in these answers. Prayer

Go to a spiritual place, when it’s quiet and empty. It be be anywhere that it’s spiritual to you - doesn’t have to be a church or synagogue or mosque or temple ... just a place that is important to you, holds a piece of you. Sit and be comfortable, letting all the thoughts in your mind go. It takes a while ... when your mind has quieted your answers will come to you in the form or manner that you will recognize.
You really need to calm yourself.
If you cannot, please call a suicide prevention center as a precaution.

Sometimes just living is the hardest thing to do. I agree with others about seeking professional help. I didn’t do that after my daughter died, and the grief and fearful feelings stayed with me for years. During my divorce, when I felt like I could not live another day, I drove myself to an inpatient treatment place. Please try to get some help to survive this crisis time in your life. Other things that can help are exercise, just walking outside, or going to a beautiful place. Meditation, yoga. Do things to distract yourself, like a craft, or even coloring. If you are religious, prayer can help. I’m Christian, and read the Bible a lot. If you can think of something else for a little while, it can give you some relief. Antidepressants helped me, which is another reason to seek professional help.

I make an appointment to see a psychiatrist.

You might need to see a professional. I recommend this if you have no other avenues. There's no shame in this, and you have to make sure you're okay.

I’d say if you’ve tried every option the only one left is to buckle down and put one foot forward and then the next. It’s easily the most painful thing to do but if you are able to keep it up and keep moving forward then in the end things will be better

I would seek professional help. After We lost our son, it took me about a year to finally seek help. I never let myself grieve and things just got worse. My job suffered, my life suffered and I was miserable. I spent 4 months in counseling for PTSD and depression.

Nature

Drink

I would say a grief counselor.

I think people deal with things differently. Some walk at the beach. Some meditate. Some pray. Some drink or do drugs. Some move away to start fresh. Some isolate themselves from society. Some volunteer to help others to get their mind off their own pain.
Obviously some of these ways are never good. Some are good regardless. Some may help some people for a bit but I always wonder if they truly do.
I would say professional help. There’s nothing wrong with seeking help.

I would go out to desert, and be alone, listening to Mother Nature, meditate, and move on.

If support groups aren’t working, you may need to talk to a professional one on one.
