Moderation!
Ishen, while I appreciate that in the start of your post you were trying to be humourus, making jokes about death and ghosts around someone feeling as Ghost rider is is an extremely! bad thing to do.
Encouragement is appreciated, but remember that people don't write messages like Ghostrider's to be funny, and that what you say matters, and this is not a time for jokes on those sorts of subjects.
Consider this an official warning.
@Ghostrider, there's not much I can say since yes, I've been there, but saying "well it'll get better" probably won't help you right now since I'm guessing your in a position where you canot perceive any difference to your current situation.
Therefore try to take care of yourself, practice some perciveerence, like Frodo plodding through mordor, then when you are feeling less bleaque in a while, consider how you can help things in the future, what you can do when your feeling like this and how best to cope.
You cannot change your circumstances, or what you feel, but you can attempt to live with it and master itand change what you do about it so that you don't hurt yourself or anyone around you.
One tactic which does help is trying to separate yourself from these perceptions. When you start to think "I'm worthless" or "I'm useless" try to recognize that these are not real or true or accurate judgements, anymore than the judgements of a very prejudiced person are accurate, think of them as "your shadow" or "your enemy" or whatever way you find useful to separate yourself from them, so that you are in control of what you feel not the other way around.
Also feel free to come and have a good vent, if this forum and this community can't really help with much else, we can at least help by being there while you get out what your feeling.
Take care of yourself, your worth it even if some parts of yourself don't recognize that.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
