I really think that you need to shift into neutral for a bit. You are excited to get out on your own as all of us have been. However, you have some extraordinary circumstances that some of us have not had. I find it difficult to believe that your grandmother would truly try to do you harm and she may in fact be trying to help you succeed when you do get out there in the world...on your own. You yourself said that you have a learning disability and have demonstrated that you are way to trusting as evidenced by your willingness to move in with total strangers the same day that you met them.
I looked up the Lifenet Wisconsin website and it appears that you may have a really good resource in them. You may want to try to work with them in getting your own place for a number of reasons. One is that the housing that you could move into. Many times the landlords of apartments that work to house people that are involved with companies like Lifenet are more forgiving of small errors. I'm not talking about not paying the rent, but in the other things that can and do happen when folks move out on there own for the first time such as paying for unforseen items like trash removal, heat, hotwater, noise levels, parking of guests, etc., Lifenet has a service so that someone can drop by and help see what things can be done to assist you in making a transition to living on your own easier for you in the most cost effective manor to you.
I know that this is my opinion, but I don't think that you are ready to step out on your own right yet. I say this because you can't tell me why you have a payee/fiduciary and you can't tell anyone the where or how your money gets paid out. To be able to be successful at keeping up with your expenses you will need to be able to know where your money is and how to budget whatever money you do get and to forsee extra expenses. I know that you are young and to you $780 a month seems like a lot but it is not.
Another concern that I have is that your 'friends' that you are going to moving in with. One of the most difficult lessons that someone can learn is that 'money has no friends'. This means that if one of your friends (or both) get in a bind--they may try to trick you out of your money. By history--your own telling--you are to fast to trust people and have made no effort to account for your expenses and income. Do you know how to read a bank statement? Keep a checkbook? Balance a checkbook? What to do if your toilet gets plugged and won't unplug with repeated flushings? Obtain a drivers license? read a receipt? know how to pick out a fake receipt? divide up a bill for your fair share? Can you safely cook for yourself? use a laundromat? Get to a laundromat with a load of clothes? What to do if your water doesn't work? Know what to do in an emergency? If a piece of the ceiling falls in? Can you take a bus? What do you do in case an apartment neighbor gets confrontational/argumentative with you? How are you getting to and from the grocery store? Can you shop? Can you budget your money effectively? I think you get the picture.
Life is hard. So take steps to make it easier. I think that if you talk to your Grandmother in private about wanting to get out on your own--she may be willing to help you by teaching you these things without interference from others. Grab the reins of your life--begin by learning about your money and how to use it. Contact your payee/fiduciary before you do anything.
