If you commit suicide does god shun you?

Well in Islam you would be sent straight to Hell even if you were a saint

Commiting suicide is a cowards way to escape

Quick answer:  Nope.

From a logical point of view, there are so many tangibles and intangibles that can mitigate responsibility for that decision.

Suicide as Tatianna points out is a very serious matter, it should not be taken lightly. The problem with it is, that it's a weak way out, often when under depression, which can be helped.

As far as God goes, he'll pay the same amount of attention to you, as he did before it was attempted.

Only God can fully understand the role of mental sickness, extreme stress, even genetic defects, in a “suicidal crisis,” which, the National Observer noted, “is not a lifetime characteristic [but] often a matter only of minutes or of hours.” Granted, one who takes his own life deprives himself of the opportunity to repent of his self-murder. But who can say whether one driven to suicide might have had a change of heart had his fatal attempt failed? Therefore, one cannot speculate on what future a person has who has committed suicide. Only Jehovah God and his appointed Judge, Jesus Christ, can say what was in the heart of a person who ended his own life. The important thing is to commend the dead one to Jehovah, the “Father of tender mercies and the God of all comfort.” (2 Corinthians 1:3)

We can be thankful that God is a loving and caring person and he understands all that leads up to a person taking their own life. No one could ever say what God is going to do if it is not written in his word the Bible. We can be sure God is going to do the right thing for all. Deuteronomy 32:4 " For all his ways are justice."

1. I do not claim to know anything of how the gods think.  Even from the all various religious texts on the god of Abraham, I would never dare to presume how it thinks.  The gods are even greater than us than we are greater than an amoeba.  I would like to think, the gods will look at the soul of the person, looking for love, caring, willingness to sacrifice for others, ...  Do they??  Well if what I know of Judaism, Christianity, and Islam is right and they are right, then what I hope is has no validity.

2.  To say committing suicide is an act of cowardice is the height of stupidity.  This is equivalent to saying since having sex is called making love, so if you say you love your children you are really saying you want sex with them.  Rubbish.  There are many reasons for committing suicide.

3.  Reasons for suicide:

Depression

Protect others

Terminal illness

Terminal illness with extreme pain

Extreme pain

Protect family honor

Running from problems

Act of contrition

Act of forgiveness

...

Yes, running away from your problems may be an act of cowardice but for those that are religious, attempting suicide even when running from your problems involves courage.  For the religious there is a future after death.  They may long for it but all also fear it.  What if their god rejects them.  Damnation will make any problems in this life seem tiny in comparison.
