Heya, I can kind of relate. I've had severe depression for 19 years and have been on most of the meds you mentioned there, except the maoi ones (if you have a history of ODs they wont give them to you here). Yeah it sucks when none of them work. I have the horrid constipation too but nowhere near the degree that you had, wow! That would be really difficult. Maye you could give the different diets a go. They didn't work for me but i hear for some people they work wonders. And some people say fish oil works great too. I forget the name of the vitamin/mineral that is in it, but a lot of people swear by it. As for me, I have accepted that this is the way my life always will be (I have been like this all my life, i dont know any different anyways) and I am just passing time now until I get old and die, basically. But you are a lot younger so you still have a lot of time to try out all that other stuff like diets etc. I always say, don't knock it till you've tried it! Oh another thing you could try is acupuncture, I heard that works well for a lot of people too. It doesn't hurt to give them a go! Well I just wanted to say you are not alone, basically.
