Hey, I've been there and got 1/2 way through a suicide attempt. GD didn't trigger it, it was other personal stuff as I had battled depression almost my whole adult life. I'm on the other side of that now and am very glad I didn't succeed. Life has become fuller, richer, and more loving. I've been through about 6 counselors during all that depression time, the last one I was with after the attempt changed my thinking. Or at the least I was ready to hear it. Remember that depression is all in the head, a real head trip! The only thing that will get you out of it is to learn to control what you are thinking.
Above all else, "Don't believe everything you think!" Think of something that your grateful for. Everybody can think of something, your last good meal, a good nights sleep, a roof over your head; something. And try to do this as you fall asleep, think good thoughts and push the bad ones to the back. Say to yourself, "I don't need that right now." Your inner self becomes the gate keeper, the watcher, of your thoughts.
When you wake up, again think of 3 things you're grateful for. This will start your mind on the right path for the day. Look at the good in everything. Ignore the bad, yes it is possible with practice, lots of practice. Have faith that the day will be a good one. Again, practice, practice, practice. You didn't learn to walk overnight, or ride a bike. Like almost everything worthwhile in life it takes practice to become proficient with it.
The mind needs training to not let it wander willy nilly. I know this from very deep and long personal experience.
Learn to meditate. This too take practice. It's not some kind of magical mind trip. It's a way of controlling your thoughts. I've been doing it for years now, and can really look back and say that it is helped me immensely. Google "meditation" and do some reading.
I know you can do this. Maybe not by yourself, a counselor is a good choice, find one that you are comfortable with. I think most will accommodate a free "get to know each other" short visit.
And you are invited to PM me anytime you want to ask a question.
