It's all true. Unfortunately sometimes is the hardest way, the only way. I personally asked my Dr. to put me on Suboxone because my depression was so bad, that I definitely decided to end my life. At the time I was on 2 different antidepressants (Lexapro and Endep, max. dose). This is not some pathetic try to be a "victim". This is a fact.
I had more than enough Amitriptyline (a few hundreds pills) and already wrote a letter to my kids. That was my last try to find something that will end my misery. As you can see, several months later I am still here, thanks to Suboxone. People often use the phrase "It saved my life". In my case that literally happened.
I can't think about the future and possible side effects. I am grateful for every new day, especially for waking up in the morning without suic**** thoughts. I get a general idea what are you talking about, because I had same experience with Oxy. After more than 10 years of abusing it it became my biggest enemy. To cut the long story short, you are absolutely right. But... There are some things in life that we can't control. I don't want to think about future because I can't change it. I am just trying to live my life in peace, on a borrowed time.
