Me and my Fiance split up a little over 2 months ago and since we split I haven't been able to really eat, eating makes me sick anymore and I've lost a considerable amount of weight since. Now he is working to better himself and find himself so that we can be a family again but I'm worried about my weight and not being able to eat without getting sick...... anyone have advice? these are b4 and after pix.
