DONT GIVE UP SOMETIMES PEOPLE NEED TIME TO THINK THINGS THROUGH
I agree don't give up. You can also reach out and create permenance in your life with people who may not be prepared to adopt but ARE prepared to be there for you permenantly. This is on FosterClub's website. Check it out.
My husband's parents are my parents now-- so I have them as a family. There are many people like me who would like to foster/adopt older youth-- however, I am in college now, so I am usually studying or working. BORING PARENT alert! Getting involved in community events , sports, church, etc. can at least give you adults that will be supportive of you. I'm not sure how old you are, but sometimes there are others around you that need a family too. I trust that one day you will find your family.
