Ok...I'm shocked. How did you get to such a mono strict diet and your father not know? I'm like forever explaining my eating choices to all my family because they are so concerned with all the weight I've lost! I need to keep reassuring them that I am eating.
My question...is your father so nervous because you haven't been sharing all along and the only thing he is seeing is your weight loss? I'm trying to understand...not be in your business. I just know...even though my family all say...they couldn't do it...they know exactly "what" I'm doing. Because I have shared.
Have you not shared at all...and been away at school for months just to come home changed? That could scare any parent...especially if you have changed physically from what they are used to. ;) Not that I feel you have done anything wrong, but I'm trying to help you understand from their perspective maybe.
Perhaps...it would be best not to go home at all. You seem very upset by all this expectation being put on you and the emotional stress you are putting your body through just isn't worth it.
Give yourself some peace and make a decision you can comfortably live with. Like RawNora says...none of us know all the "background" on this relationship with your dad. So...we are just throwing out ideas...hoping we hit on one that will help. ;)
Just for the record...I'm really proud of your accomplishments in Raw! If you are this far along...don't wound your body by eating cooked food. (I know I just can't go back...ever.) Just don't throw away your education either. Secondly, if it makes you that nervous to go home and have a confrontation about it...don't go. Visit your family when it's not a holiday. Or before the holiday. Celebrate with time spent, not food eaten. Raw (((HUGS))) You are in my prayers.
