Is it normal for this family member to be like this?

Firstly, I'm sorry its so long.

Ok so the deal is that I am currently not living with my parents, BUT I am living with my Aunt and Grandmother at the moment, I haven't lived with my parents for more then (I think) 2 months, 3 months max, at a time.

Now to the problem...My Aunt has this tendency of talking me down a lot, she rarely gives me praise or anything positive. She always picks me up on anything and everything she can pick me up on and the smallest things, and always puts me down. She basically wants me to be the perfect person I'm not or to be like her, she wants everything so damn perfect, everything her way and she never lets things go (as in if there is something she wants me to do myself she will push me and push me to go do it)

I do understand what she is trying to do, she is trying to help me, and I do know that I can get a bit lazy and what not but surely I don't have to put up with all day every day, in which I do.

I have thought about leaving but she thinks I wont be able to cope and that I will struggle with getting a job as I'm struggling at the moment with the job I have now.

I have talked to my my Mum about her and she somewhat agrees with me and understands what I am saying so its not like I haven't talked to anyone about it.

Is it normal for her to do this and is it normal for me to start not liking her as much now?
