I'm pleased your Dad was supportive and, I hope it helped and continues to help. Sometimes, it is nice to hear that it's ok- even if you've made a mistake.
Yes, my Dad also says that kind of thing. That I'm 'precious'. Mostly that 'you need to take care of yourself because you're precious'. (Like that damn ring in Lord of the Rings- lol.) Obviously, it would be way worse if he didn't care but honestly- it probably doesn't have the effect that's intended. All I tend to feel in response to that is- don't worry. I'm not going to kill myself until you've passed.
He will also say that he'll support me but I know that would come with a whole addendum of guilt trips ultimately so- it doesn't actually feel all that supportive. Maybe he'd be different if he knew just how much I wanted to kill myself but, I don't think that would help either, seeing as I don't feel like I can. (While he's still alive anyway.)
But, I do understand how someone caring about you can throw things a little. I hope things feel more settled for you soon. Are you likely to accept the offer and go home?
