Hi lostprinny! Keep coming on here and reading as many things as you can and know that you can change yourself (even if no one else will change themselves). After a while, (and trust me I know), you will be able to let others make their own choices and face their own consequences of those choices.
I'm praying for you, your mum and your whole family at this time. You're a good daughter. Big hugs to you k!?
