Your comments are insulting to anyone who has had to deal with real physical depression at a level that is seriously debilitating, either personally, or via a family member or friend.
The only thing I can be sure of is that your previous depression wasn't too serious and those whom you have spoken to either have mild depression or are actually just "sad." I think many people today think they are depressed when they actually just have a low mood which is nothing like severe depression. I've witnessed things that no son should ever have to.
I understand that your comments are born out of frustration and that it's likely you don't even mean the things you say, but this isn't the first time you've made this comparison and I don't think it helps anyone, including yourself.
I have severe "multi-sound" tinnitus that I hear all the time. My head is a constant cacophony of noise and it had me on my knees begging for death, just like you, so I really do understand your emotions and where you're coming from. I lost everything that I'd built my life around which was utterly devastating.
Life can be really cruel, Pete, and I sincerely wish you well, but comparing your problems to others isn't going to help you because your pain and suffering will always win, as it's your life. Dealing with debilitating health issues is never easy especially when the problems you are facing are new to you. We often have no choice but to look for the inner strength that we never knew we had or existed, but it's there somewhere. With the passing of time, there's a good chance that the impact it has over you will lessen but this takes a lot of patience.
It's incredibly sad to see so many of you in such pain, but I believe you can all weather the storm, I know you can. There's also a lot of potential treatments in the pipeline as well, so never say never.
