awww sister its a shame u cant share with sibs, maybe try to do it slowly, talk to one one day, tell them u dont feel too hot. try to push yourself, see how they react. im sure they will care for you and try to help. and failing that uve always got us!

sid its great that u r getting on so well and getting support from your sister! keep at it it is doing yah good i reckon.
take care all
