I am just so alone. I feel like I am going to disappear.
Go to your doctor right away and get evaluated for depression. I'm not qualified to diagnose depression but that sounds EXACTLY like how I felt when I went through it and years ago when my XW went through it she said the same thing. Depression is debilitating and even life-threatening, and it won't go away on its own. If you're in depression then it's important you get medical help ASAP.
