is it time?

So earlier my mum noticed my 'scratches' oon the tops of my arms. She saaaid there was quite a few when theres only a couple. But i think she knows, she has pulled me up before about it and keeps oon doing so. Anyway, i think its time to tell her before it gets out of hand again, its not that bad that i would need surgery but still sometimes stitches bad. But alaso i have noticed recently my mum has been very low lately. Like not asad but just low. Like she never wants to sit with us at dinner, doesnt want to be in the same room as us. And just generally wants to hbe alone. And thias isnt her at all. Its hurting me cause i dont know whatas wrong. I want to help but how can i help other when i cant help myself? And the satopping SHing is crap, cause i thought this was a distraction but i guess not. Now lets go'n asee what mess im going to do now. It sickens me with my actions.
