I'm 18 years old and I've been a little off lately, I don't feel like doing anything and most of the time I just want to be alone, I cry a lot and I feel worthless all the time, I just stopped seeing joy in everything and constantly feel like everything is against me, I keep thinking about death and suicide again and again, it never stops, sometimes I wonder how being dead must be and most of the times it sounds better than staying alive, I recently started cutting and I know that there's something wrong with me...what's happening? I'm afraid of what I might do to myself...please help me...
