While thats good advice square_eyes,the crisis care worked has only known her for a few days I think.I dont know what the right decision is either and I'm sorry if I have confused you,I just think it should be your decision to make.
Sometimes we do have to get shoved into the deep end for things to ever change,but at the same time it has to be you who makes that change imo.Whatever happens I am sure you will be okay,even if you dont like it in there,at least it gives your Mum a break,and then hopefully when things are a bit more stable for everyone,you can go back home and things will be better for everyone.But at the same time you have to remember what happens if they decide your a danger to yourself..and your Mum agrees,they can then by law keep you in.They did this to my Mum,even though she went in by her own choice,they slapped her with a section.I know your poorly right now,but I honestly dont see how forcing you into a strange place is going to help
And I could be totaly wrong,you might end up getting good help and support in there that you otherwise might of not got.
But I have seen first hand the health care people get in this country,and imo hospital should be a last resort,like it was for my Mums own saftey she went,i know your ill but i honestly think given time,you will get better at your own pace.
