I think you need to learn to compromise with your family...offer to pay the water bill, if you want to do more water changes. Explain how you prefer the wood stacked, and that it's easier on you if they do it xyz. Ask what they expect of you, maybe sit down and have a good talk about your concerns. Nothing is accomplished by running out the second you get frustrated, and don't burn your bridges. Perhaps you can secure a job, and get a routine going before you move out again.
You don't seem happy in any situation, personally I think you need to stay put until you figure out what's making you unhappy. Obviously it's not your living situation, or you would have stayed at one of the places you lived. I don't know you at all, but maybe something else in your life needs to be looked at versus where you are living. Any possibility of taking some classes towards your GED or something?
