Welcome back to MR, Cookie. What was your original username? It might help jog some memories.
I am sorry you walked away the first time with sad memories. We all try our best here, but of course we're only human. Although I can tell you that we've been pretty well draw free here for several years now. I hope it stays that way, for all our sakes.
I understand losing that passion though. To be honest, I lost almost all passion for writing myself for several years. There were a few short stories here and there, but for a long time I practically left it behind. At the end of last year though, I found myself filled with a creative energy that hasn't subsided yet. I'm working on something like 6 stories at once now because of it.
Interest will wane and wax, but as long as you keep it as part of your soul, it will never leave you. Sometimes people just drift away for a while. Even if they feel they may have lost their drive completely, the littlest of things can bring it back with a vengeance!
