Mom boundaries

Where do I draw the line with my mom? She tells me not to let people walk all over me but she does whatever she wants. I am 23 and have been thinking about moving out for a bit because I feel smothered but I just don’t have the funds right now.

I feel ungrateful because she lets me live in her house but I am 23 years old and she will still not go to bed until I am home every night - forcing me to come home earlier. I am on afternoons during the week so the weekend is my only time to see friends or my boyfriend but I have to cut my nights short so I can be home so she can go to sleep. None of my other friends moms do this.

Tonight she opened my mail which was a bill for my IUD consultation (which I am not telling her about) and was asking me what this bill was for. The mail was addressed to me yet she opened it and was questioning me about it.

Like am I crazy?
