Yes Peredhil, fear of not living up to a standard of replies to a thread scares me away from posting, possibly why I stayed away from actually reading and registering at the Pen for so long. But here I am, perhaps I can overcome that fear. Or even surprise myself and post things I didn't think I was able to write.
But as for the topic at hand, I have felt depressions in various situations, and while the causes may have been different, the result was always the same. And it sucks, to be frank. BUT, there is always a way out, and by that I mean a good way. Love, be it from a friend or a relative or whatever, has dragged me up numerous times. The times I didn't get that, I still dragged myself up through my own willpower, but it was a lot more painful.
Show your friends and family the love that you feel for them in their time of need, it really helps.
