I've never seen so much suicide...The Bible is full of hope.
Until you start thinking right, you will never start behaving right. Repentance always deals with the changing of the mind.
When a person is carrying their sin, it can be quite a load...I don't know what else to do with your sin but confess and ask God to forgive it.
If you know what you got and like it, be reluctant to leave it.
The best thing there is to do when there is temptation is run.
Apart from Jesus Christ you are spiritually bankrupt.
