For a moment I believed you loved me too
But life is never like this, and you're never strong
Too much of a good thing won't be good for long
Although you made my heart sing, to stay with you would be wrong
Too much of a good thing won't be good anymore
Watch where I tread before I fall - Sam Smith.

I hope this is a fiction, but if this is happening to you, stay strong - you are loved, not by one single person but by everyone of us.
