Mom follows me on instagram?

[xoxo]

Hello. Im a 15 year old girl, I made an Instagram like 4 months ago. And I've been hooked. My mom made an Instagram like a month ago. And she followed me. I then knew its gonna go downhill now. She's very into everything I post or write. I have to think twice when I post a picture by myself or with someone because she'll start annoying me if she doesn't like it. I have to think twice about what I put as my Instagram caption, bio, profile pictures, what I comment when others comment on my photo, ect. It's getting so annoying and I feel like I'm trapped. All I use is Instagram, no facebook, no twitter, nada. I mean I love my mother will all my heart but she bickers over unnecessary stuff. I blocked her like a week ago, because I couldn't take it anymore but then 10 minutes later she came up to my room and said.. "Why did you block me? Wow, im your mom!" And I made an excuse because I felt bad and said, "I didn't block you... refresh there must be something wrong." And by the time she did that I unblocked her. For example, a few days after that. I was at my best friend's house and one of our male friend came along and I knew him, my mom knows a little about him too. All she said about him before was "he's cute". By the way, my friend's parents was home, in case you're wondering and he's just my friend so we took a picture and thinking it would be "alright" knowing my wouldn't really care I posted it up and then the next 5 minutes she called me yelling saying, "Get home now!!!!!!!!! Why are you with boys?" Wow. I'm with one male friend, yet she goes nuts. And that's only ONE example. I honestly can't take it, I want to take pictures for MEMORIES. And it seems like it's quite impossible with my mother watching my EVERY move on instagram! What should I do?? Thank you!!
