wow, you have a lot going on right now and a lot of what you wrote struck a nerve with me (especially the weight gain issue and the 'gee, you'll get hot guys when you're thinner part'). I think you are right in worrying about yourself right now--you can't take care of your brother and parents without taking care of yourself first. please see a therapist if you can and start with baby steps. it's so overwhelming when you have so many issues at once--I know how that is. for what it's worth, you're not alone.
