I feel really guilty & embarrassed - I love my sister to bits, but she's in a really bad place & I think she needs to see a doctor, to be honest. She's got a big emotional mess of her own, plus all of her friends seem to be the sort who cut themselves & what have you. & she takes it all totally to heart & gives herself sole responsibility for their well-being & blames herself every time she can't stop them.
& now she's getting 'I don't care' about everything, which is really unlike her - usually she's a massive stress-head about school work (to the other extreme, which isn't good either) & a straight A student because she works so hard. & now it's all totally sliding & she's getting in loads of trouble & she has her GCSEs in a few weeks now - & she's just totally given up.
The problems with her friends will pass & I know one day she'll cheer up again. I was depressed through my GCSEs (in fairness, I had a much bigger reason than she does, so far as I can tell), but I had really great, supportive friends - she doesn't. They all seem to think that it's somehow a teenage rite of passage to give up on life & let opportunities like getting really good exam results with very little extra effort from this point slip through their fingers. It feels like they're trying to out-misery each other. & she's caught in the middle of it & is genuinely really messed up & does nothing but cry a lot of the time.
My parents aren't oblivious to it, but don't know how bad things are getting because she doesn't tell them. She confides in me a bit more. But now she won't, because she knows that I phoned my mum to tell her about it all - & it's the first time I ever have & I really debated whether or not I should. I'm really angry with my mum for putting me in that position, even though I know it's my own fault really. I'm hormonal & I'm blaming her, so nerr.
