Listen, you are not a computer so that you can reboot the life game you are playing now. Once it's gone that's it and remember death will come to you when it is the right time for you.
For you what importnat now is to find a way to solve your problems and I hope there will be a way for it. Spend time with some of your good friends, go out with them, read good books, pray regularly and eat good food. Think of your daughter, wife and your parents who are relying on you.Once you take your life, there is no coming back.If you are considering something as drastic as ending your life then you must speak to counselor.
May God bless you!
