I'm not sure what I can add. I guess by now you can see that you really are not alone. Neither am I.
I've tried sometimes to be supportive and positive and so on in my posts. Every once in a while I'd write something that I didn't really recognize. I don't know how many times I wrote messages, reread them, and then added something like "I don't know why this sounds so depressing, because I don't feel like it sounds at all" before posting. Or I didn't even post them. I can be different by the time I finish writing.
I'm glad for you that you post the messages when you're on "the fast track." I reached a point where I'd try to keep all those messages to myself. That actually led to me not being active here until I revived an old, dangerous behavior a couple months ago.
Better here than there, so I try to be more active again. It's working so far for me and I hope it will work for you, too.
