Why am I doing this? It's like a form of self harm?

I don't know why but maybe you're somthing like me and you get attatched to other people easily. Maybe they make you feel like home or something, like they are a part of your life and you want to hold onto it deep down inside even though the memories were painful. But you have to let go!!! It's difficult, but you have to do it. The next time you get the urge to check their profiles, resist it. Build up your self-control and surround yourself with positivity! :)
