I am glad to hear your depression is situational and not clinical, this means you can treat it yourself versus having to get on medication. But I am sorry to hear you are in a bad situation right now - as you pointed out tho it will change so all you have to due is prepare yourself for that change. Since you are/were a churchgoing type person maybe you could begin by replacing the church you left with a healthier one. That would do a lot towards easing your loneliness. You know you don't have to be alone if you don't want to be. I'm sure there are churches that would welcome you with open arms. Good luck in your search.
