<human>: I'm an only child and my mom has always smothered me. I'll be graduating this year, so I don't know if she's trying to prepare herself for me getting a job and moving away, but she's been out of line recently. Here's just some of it:

When I'm at school, she calls me sometimes multiple times a day "just to check in" and she basically interrogates me. I'm responsible and I haven't gotten myself into trouble since I've been away from home, but she thinks I'm keeping things from her. It's gotten to the point where she has added my friends on Facebook and messages them with a bunch of questions about me and what I'm ~hiding~ from her.

I tried to call her out on this and asked her to stop harassing my friends, but she still does it. Most of them have just blocked her, which set her off even more. She doesn't think that she's behaving crazily and has no respect for boundaries.

She constantly yells at me for not acting more like an adult, but she refuses to let me do anything by myself. She changes the login info for my bank account all the time so I can't get in and pretends to be me on the phone. It's ridiculous. She also insists on coming to all of my doctors appointments and the nurses always think they have the wrong birthdate on the sheet because my mom is in there with me, but nope, she just refuses to accept that I'm not a minor...

I got into a fight with her today because she wanted to come back with me at the dentist and I asked her to just stay in the waiting room. It was a normal dentist appointment too, just a routine teeth cleaning not oral surgery or anything she would be concerned about. She threw a fit and it was mortifying. 

I understand that she cares about me, but she is stifling me and I don't know how to deal with her. I'm really losing my patience and would appreciate any advice!
