I'm 20 years old and I live away from home and I feel like my mom is way too controlling. I get that she loves me and wants the best for me, but she does things like read through all of my text messages and always wants to know exactly what I'm doing online and see what websites I've been on when I'm at her house. And when she reads my texts, she'll get mad at me if there's something in them she doesn't approve of, even if it's just a stupid joke or a swear word. She also posts pictures of me (some from when I was a kid, some recently) on Facebook on a daily basis with similar captions each time (things like "I love my sweet baby girl!!! <3") even though I've told her I don't like having hundreds of pictures of me online multiple times.

She has always talked bad about any friends or boyfriends to me, as if she's trying to convince me that they aren't good for me. Not one of my friends has been good enough for her, even though she acts perfectly nice to them when they're around. Telling her about anything from a new friend to a new interest of mine makes me anxious because I know there's a good chance of her not liking what I have to say and not letting me hear the end of it. Is there anything I can do to improve things with her and set some boundaries? I want to have a relationship with her, but I don't want it to make me be on edge everytime I'm around her.
