I am so sorry you do not have your bio parents BUT your lucky you do have a grandpa who loves you. Yes, possibly you will be more independent but the coldness is up to you. Be good with yourself be kind to others listen to those who teach the good. Say your prayers our lord knows what we need and he can give you some answers. He loves you too. Do not allow anyone to do anything uncomfortable to you talk and keep talking until you get your needs met. Do not be afraid! nothing in this life is easy. It is what you make it to be. Choices stick with you forever be safe and not vulnerable to others.
