I'm sorry hun, it can be really hard having to hide all that kind of stuff from your family, emotionally draining and often makes you feel worse. Stay strong sweety, not for your family but for yourself, don't just 'keep it together' on the outside, try and remind yourself how strong you are to have gotten this far, and to have asked for help and to be trying so hard to make things better for yourself and your family.
If all else fails remind yourself that's it's not for long and slink away to get online to RYL as much as possible.
I hope it goes ok hun, take care xx
