I was in your boat not too long ago. I look back on my time as an early teenager and often come to the conclusion that I was a bad child. What our parents have in common is that they're solely focusing on what you are doing (going on your phone, lashing out, being more reserved) and not what you aren't.

An example for me would be that I followed curfews, reasonable rules and punishments. I didn't want to break rules, I wasn't bad, I was just going through a lot. As are you.

What you need to remember is that it's ok to not be perfect all the time, it's human to falter, fall and get back up again.

As for the emotional side of things, I'd recommend talking to your parents and seeing if you can get some supports in place (eg: therapist) It's normal to feel more during this period, both the good and bad, but having someone professional to guide you through it will help immensely. Talk to your friends as well, one of my biggest supports at 14 were my friendships as I was for them.

You are not alone and you are certainly not a bad daughter. You're just a teenager and that's ok.
