Worried about changing my profile picture on Facebook?

[Phoebe]

I've had the same profile picture for probably nearly a year and it doesn't really look like me. I'm nearly 15 so I've changed a lot since it was taken. I don't have very much confidence but I prefer myself in the one I want to put on Facebook rather than my current one.

My boyfriend and his best friend are being quite mean to me recently and they are saving all of my old pictures and profile pictures on Facebook and sending them to each other. They've been laughing and talking about them and being really horrible. I kind of want things to end with my boyfriend.

I'm scared they'll be mean about my profile picture how do I stop worrying? Should I change it or not?
