The proverbial Psych Central lifeline is duly tied about your waist and anchored to the shore! Hang on!

I'm sorry you feel so bad about whatever is going on in your life right now. I'm also sorry you are alone tonight.

It isn't the end of the world. I know it must feel like it, from reading your post. But it isn't the end. Maybe it's the end of a type of response you have given etc, and a new way to relate to this person begins tomorrow?

I hope you don't cry yourself to sleep, but you do need to sleep and not make any more decisions tonight. The sun will come out tomorrow and the light it shines will give you new insight, and more strength to get through this.
