Hi there hunni,
Im really sorry that you feel like this. I think its terrible that you should have to feel this way and feel that you have no choices. I am a little confused as to whether you have sent this letter/email to your parents or not. If you havn't then I think it would be a good idea to let them know how much you care about them and how you feel about the situation. If you have sent this then have you received a reply? Also, does your boyfriend know how you feel? What are his feelings on the matter? Perhaps a compromise can be found? For example, moving to a state half way between Florida and Iowa such as Kentucky or Tennesse? I am unsure why he is so adament about living in Iowa.
I ceertainly dont think that you are stupid in anyway. We all have to make our own way in life eventually and there will be times when we feel we have made a mistake and times when we know we have made the right decision. This is all part of the learning process, but doesnt make you stupid.
You know that we will always be here for you to give you the support you want and need whenever you want.
Im sending you big hugs from the UK
