Alvah, get the depression dealt with through counseling and/or meds. Until that is done you wont see things clearly enough to make long term plans. For today, just get through today. Not sure what you mean that marriage #3 is "on the rocks". If it's over, then it's over. If not, don't end it yet until you get yourself straightened out. Work toward no longer feeling like a victim. Eventually you must identify why you do not have many good relationships. Own the part of it that is your fault and work to improve it. As long as you live there is hope to improve these things. There will be a way forward. You just can't see it right now. I see you quoted scripture. If you are in a church, meet with the pastor very soon and let him know of your struggles. Hope it works out well for you.
