I hate what you are going through. Has it occured to you that you might be living with an immature, self centered and possibly mentally ill adult? I'd like to add that he may a self esteem issue. Parents aren't suppose to behave that way. It shouldn't matter what personal issues you might have such as weight, purple hair, tatoos or 6 arms. You need to be loved unconditionally. Try to focus on a future and a place where you can decide who lives in your "space" and how you will be treated. You can and will get there.
