I want a website specially made for that purpose. Like there is one named mymiserablelife.com but I don’t know how it operates. There is no about us or contact link. Is there any other like that which can be reliable?
Google "the experience project". It may be what you are looking for.
I think the real question to ask yourself is why do you want that? I don't think we need a web site designed to help us wallow in our grief any more than we already do. Try doing something nice for someone else instead.
just write status on Facebook and get reply in a seconds. You'll be no more sad and feel sorrow. :)
