Hi Lostsomewhere, and a warm welcome to the forums.
It's always so sad to hear people who have been struck down by this illness, and yes 2016 is three years ago, but that doesn't stop how you are feeling today and the situation you see yourself in, I'm sorry for you.
To post a comment isn't easy because you're not sure what you need to say, that's natural and happens quite frequently, so just start gradually, tell us why you decided to come to the forums, a bit about your depression and certainly about these thoughts you maybe struggling with.
The people on this site have been through their type of depression and know what suffering is, so take your time and tell us what you want to.
Best wishes.
Geoff.
