I'm sorry to hear that things didn't work out for you ... And maybe it seems like things are hitting you all at once, and its really overwhelming .. but you have to believe that there isn't "something wrong with you." ... I myself have a hard time with feeling and saying those exact same words ... but i know that if you can overcome them, and stop believing all these negative thoughts.. the future won't seem so inobtainable. Try taking some time and doing things that YOU enjoy. It could be as simple as drawing/singing/reading/listening to your favourite music .... anything really, but take some you time, it may help the sleeping a bit at night.
I'm sorry if none of this helped because i am struggling with many of the same things .. but know that we are all here for you, and i sincerely hope that things can get better for you.
