I have tried 5 or 6 different antidepressants and I can’t find relief…..

I’m 30 years old I have had depression for going on 6-7 years now. It has gotten extremely bad the last couple of months. Today as I type this I am in my truck at my jobs shuttle parking lot thinking about all of the ways I can leave this world peacefully……..but I’m scared. I’m scared of what is after death. And I don’t want to give up yet but I’m tired of feeling this way. I want to power through and get better somehow because I love my nieces and nephews and want to see them grow up. They are the only reason I want to keep going. I am taking Wellbutrin (300MG) right now and all it has done is just make me able to cry. I have no happiness, joy, excitement, energy or motivation whatsoever. I am just pushing through life one day at a time and it’s hell everyday. I don’t have a single good day they are all very bad. I’ll have days where it’s not as bad but not good. I make great money for my age and rent a house. I have both my parents and 3 siblings (all 3 have some sort of depression or anxiety) with all 3 of them having 2 kids each. I am the only one with no kids………Also one main reason I’m trying hard to keep going is I don’t want to put my family in the position to where it hurts them bad enough to start making them go over the edge. I’m just looking for something to help…….SSRI’s and other drugs aren’t doing it so I don’t know what else to do. I’ve tried going to an actual mental health DR. and that didn’t help. She just diagnosed me with MDD and general anxiety and I went a couple of times to talk about my mental health but it didn’t help. I’ve tried a lot of “do it yourself” remedies like NAC, Lithium, K2D3, stress complex, and countless other things to no avail. All I can think about every day is that I’m going to eventually give in because I won’t ever get better and that I have treatment resistant mental health issues. I’ve been to 3 or 4 different Dr’s and none of them seem to care to dig any deeper than just throwing more drugs my way. I need help because right now I’m losing this battle……..
