Greetings Plavious,
Whatever you do, suicide is not the answer. That should not even be a consideration. I can't say what happens to one who is in Christ who commits suicide. For the believer, at the time of death the spirit departs from the body and goes to be in the presence of the Lord. For those who are not in Christ, when they die the spirit departs from the body and goes down into Sheol/Hades in torment and flame. Like I said, I can's say what happens to a believer who commits suicide, but you don't want to take that chance. Many people commit suicide because they can't deal with issues in life, thinking that when they die they just fade to black, becoming non-existent, but that is not what happens. The problems that people are going through in this life pale greatly compared to what they will experience should they end up in Hades. The rich man of Lazarus fame who died and found himself in Hades said that he was in torment in flame. When he asked Abraham to send Lazarus back upon the earth to his fathers house so that his five brothers wouldn't come to that same place of torment, Abraham said that they had Moses and the prophets (word of God) to warn them of that place, meaning that no one could return from the dead and warn anyone living on the earth.
I will pray for you and your family that God's grace and His mercy will be poured out upon you and that He will be the Lord your provider. Remember, there is nothing in all creation that is hidden from Him. All things are laid bare and open before Him. Even the very hairs of your head are all numbered. So he knows your situation. And, all things are possible with Him, nothing is impossible.
Continue to pray about your need and anticipate and wait for God's provision. But get suicide out of your head. I'm sure that there are many in Hades who wish that they had problems of life opposed to what they are suffering now.
