not even brave enough to end it

The truth is, that it takes great! strength and courage to end ones life..
Just the same as it takes great strength and courage to live it..

For your relashionship problems,
I Highly recommend you Read some good
Psychology as i think it would be highly beneficial.

i highly recommend you read

{Dr Eric Bernie :
Games People Play: The Psychology of Human Relationships}

{ Carl G Jung#..all his work is worth researching}

{ Melenie Klein# read her Psychoanalysis Of Children},

Melenie Klein was a pioneer in child psychology & this book i guarantee you will help you trace back to & learn where all your traumas and problems lay and started, you will be surprised how far back these traumas etc start..and how much these early deep seated problems effect you and your life (relashionships)

And after you have some insight and are aware of your
psychological problems,
go and do some self cognitive therapy .

Aaron T Beck was the father of cognitive therapy

some of his works / books ,

The Diagnosis and Management of Depression
Cognitive Therapy and the Emotional Disorders
Anxiety Disorders And Phobias: A Cognitive Perspective
Cognitive Therapy of Depression
Prisoners of Hate: The Cognitive Basis of Anger, Hostility, and Violence

You have some tools to heal yourself..
it will take a little effort

but the bottom line is, life is hell!, and hell is other people..

Either you get busy living.. Or you get busy Dying.
