I know that sometimes there's no stopping thoughts like that coming.......depression can lie to you in the cruelest ways........but just remind yourself that a "simple" thought doesn't make something real, hey??
And you know, I'd say that it's possible that the act of them paying for meds and therapy says the exact reverse of what you're feeling they think........maybe with that they are thinking positively about you.........that you're worth everything it may take, to them, that they do see you as special, that it is an act of love, because they love you and are thinking anything but negatively about you/about who you are
